I'm glad you guys decided to make this. I always wanted this period of time to be explored since it was skipped and this feels like a really nice add on to Adastra. Good stuff overall and it's making me appreciate Amicus more.


I like the point of contention between Amicus feeling embarrassed after the match and Marco wanting him to be safe. While Amicus seems to have a good intent in wanting Marco to be honest in saying that he should feel embarrassed by Amicus' defeat, I cannot help but interpret that Amicus wants Marco to feel embarrassed for him so that he does not need to ask himself why he's embarrassed. To distract himself from confronting his own feelings alone and instead blame Marco for having similar feelings in the future. 

It's likely that the loss, coming at the expense of his pride and ego, makes him feel like he is unworthy of being an emperor or that he cannot protect Marco sufficiently. 


hey, why does amicus look different? The original was so good :(


time has passed


I wish Interea update frequently like Adastra once per month or two in the past patreon.
I know there is many CG need it for Interea. but we came here for the story and Amicus.

You guys don't have to push the limit and forcing every update to be better than before.
On average we definitely choose to update frequently rather than every 5 months
if so sacrifice some CG for the faster update
Maybe, every update do not have CG, maybe 2-3 update ? it's fine guys.
I really scare this game take 3-4 year to complete, if you still use the previous update schedule

I saw a screenshot and it was 1.0 version in main menu


I agree. Many visual novels may leave some BG's blank until the end of development. While, that may not be a very immersive choice, we could also settle on "placeholder" BG's, another common choice for VN's. Even after reading a little bit, I become reimmersed into the story, I cannot say the same for other VN's.

You have to realize that the devs and the artists are now older with a lot more stuff to do. Jobs and lives. I'm pretty happy with 2-3 months updates. I'm willing to see this project until its end, and yes, that includes Khemia and whatever the inevitable part 3 finale will be after that as well. The quality these guys put up is very good so it's always worth it.

Does this game have a discord server?



Wish u could get with neferu😏

I finished reading Astra and went straight to Interea, I imagine this story happens after the return of the human, but it is my speculation. I must say that I liked the situation, and I am finding it very interesting to observe and learn from the political situations of this Moon. Please keep up the good work by adding more to this rich and amazing story.


This is before the human departs from Adastra, before he goes back to earth

anyone know when the update is being released?

Id expect another month or so


Finished Ad Astra recently and I'm so tempted to dive into this, but I really want to wait until it's finished. Just have no idea how long that'll take. (the parents really weren't joking about that eight years)


Honestly It would be better to read now. They probably wont finish this for a loooong time


I m just jocking...no one can't step in the beatiful love between human and Amicus... 😍


Magis maybe want threesome .... :D


I don't think Amicus would comfortable doing that and usually when he wants to make love, he would only do that with Marco, but hey maybe. But what I said right now is facts

Pretty sure neither Marco OR Amicus would agree to it. I mean remember how it went in Adastra during the "deal" Amicus made with Neferu

Well, that was because it was behind Marco's back. While, it was for Marco's safety, it almost seemed... primal... feral. I'd imagine that'd be quite hurtful to see compared to a mutually agreed upon threesome


In the natural springs, i thought that they were gonna make love and I was so exited for that. Then Magis came and ruined everything. Why Magis? WHY?!


He was planning to taking advantage and meet with Amicus and the MC privately for a little bit. I'm sure he never expected Amicus and the MC to have sex. Seeing that it was about to happen, Magis had 2 choices, interrupt them before or after sex. I think he made the right call interrupting them before anything happened.

Queria saber se ojogo interea e a continuação do jogo Adastra

Não é uma continuação como tal, vamos chamá-lo de intermediário. Interea narra a jornada de Amicus e Marco (o personagem principal) através de Adastra antes que o humano retorne à terra.


I may have forgotten but, who do we play as in interia? do we play as the human form Adastra or

I think it is the human we play as in adastra.

Oki doki! well, i hope the same thing wont happen with magis that happened with neferu.. it was heartbreaking when the human saw it..at first it could be understood but the human and amicus are now in a relationship so..i really hope it wont happen lolo XD :w:

it s so funny Amicus is shy among Mangus but it s ok when he f*ck Neferu...lol

Its unallowing me to open the files for the new update for Interea on Android. I'm unsure what to do since I had deleted it and downloaded it over and over again.


Love the new part! But . . . I wasn't a fan of Amicus's facial expressions when Mangus appears at the hot baths 

(1 edit) (+2)

Just played it,  I'm excited to see where it goes!


Finally a new update, and I love It!


omg this caught me off guard 

OMG...downloading it now

I realize this is not done yet, but if I wanted to start playing this chronologically with the first game, where would I begin?


Adastra, then this game.

Is this game dead??  This game is so amazing


No it's not dead. Patrons, like myself, get early access to the release before it goes public. Not sure if the public release is the first or 15th of the month, maybe someone else remembers.  

You should be getting it soon. There is also a lot of new background artwork and CGs made for this build, so it took a while to get it done.


Yes!, the patron version for build 4 came out this morning. I enjoyed it quite a lot, but of course I wish there had been even more. To avoid spoilers, I won't say any more.


So... any news about Interea?

(1 edit) (+1)

In Patreon on May 3rd, they provided 3 GC's (not colored in yet) of Amicus at the hot springs. So work is still being done, just too bad it's not faster. But I appreciate that the story is still advancing. 


I appreciate that too. After all, waiting means something.  This serie is really something else compared to other VNs.


Does anyone have the same problem as me? When I go for the fourth dialogue, the game suddenly crashed! And the game seems a little laggy. I download the game on an android phone called Samsung Galaxy A12 btw. Help me fix pls, I want to read it so bad!


Maybe the files are corrupt. Have you tried deleting and redownloading? The A12 should be able to run this game just fine.


I've tried, but it does not work! It happens with the Echo and TSR as well. But I can play Adastra, how weird. 

Will this ever be released to iOS?


probably not


Doubt it, you can't officially run files not from the App Store on iPhone.

They could use TestFlight

I’m happy to see them together again, although it is not fully finished I have enjoyed the new change between both of them. Maybe we will see a full wedding?

So far the story is intriguing and finally the challenge I had on the previous Adastra story line. Revealing against the redacted is a welcome change to finally see who are redacted.

enjoy this while we wait for the update 


Im crying right now😭😭

Do the updates come like a normal app update or do I have to manually seek it out? I'm using an android phone. I'm stuck between really wanting more of my lavender man, or waiting for it to be complete...


We cant wait for the next update ❤️

Should I read Khemia before reading Interea?


interea is part of what happens when your character in the first game finally gets to go exploring the cities of adastra. 

where in the timeline is this in relation to khemia and adastra?

Deleted 144 days ago

thank you


No, not at all. 

This visual novel is not a sequel at all.

It's a companion novel to Adastra, focusing on the Moon Tour (in the game, this event is merely summed up in a few lines).

thanks after playing it this makes more sense 

(1 edit)

OK, so Interea takes place during Adastra (particularly those times when many months pass, because almost at the end of the game on lovers day, after Amicus and Marco "got intimate", the game suddenly went from Marco having quite a bit more time left on Adastra to barely a day left) There are obviously many more time-jumps throughout the game but I can't think of all of them now. Basically Interea takes place during those missing time gaps, correct?

Do we know how long Khemia will be on hiatus?


Until Interea is over that's for sure, then, who knows?


Interea is supposed to be 10 chapters if I recall correctly. It's doing a lot to set a foundation for Khemia and for character backgrounds. 

And what chapter are they on now?

It's currently at Build 3, so chapter three.

Interea took 2 months for 1 build. So, maybe Khemia will be on hiatus for a year or 2 years.

is this a sequel to Adastra


It's a midquel, it takes place during a timeskip near the end when Marco and Amicus go on their trip.

Khemia is the sequel


I don't know about you guys. I'm not getting any hype on the new sprites. I'm not saying I don't like it, or hate it no no no. It's just that, it feels different, like they are different characters now. I got emotionally attached to the old ones which makes it really harder to get used to this new ones.


I was the same honestly... and still is.. ajdfhskjfkj I feel like he lost his goofiness and immaturity which is supposed to be true! considering he is emperor now but I just feel distant when going through the novel. I am still trying my hardest to  see amicus in the new ones and sometime I can but most of the time I can't. I've been through interea a couple of times now with the new sprites in it (trying to get used to it) but nothing really changed.. can't really blame someone who got really attached to the old sprite. especially for those who just found out about interea after adastra. 


The new sprite for Amicus should have only been used for Khemai. At least that storyline takes place three years after Adastra, which would explain the change in looks.

hello, would it be possible to put other languages than English, because unfortunately I do not understand all the dialogues because I am French and then it would be great for those who are interested in the game like me.

Si tel est le problème, je vous recommande d'installer une traduction d'écran, la traduction n'est peut-être pas parfaite à 100% mais au moins vous pouvez comprendre une partie de l'histoire

Could you tell me that she can do that?

Hi, French fellow! For my friend's comfort, I'm going to type in French, so English people, sorry, you won't understand a thing:

Malheureusement non, ce jeu n'est dispo qu'en Anglais. Sur certains autres jeux, des paramètres de langues peuvent être modifiés, mais c'est rare, souvent c'est compliqué à réaliser, et en plus la plupart du temps les seuls choix possibles sont Anglais/Japonais.

J'aurais aimé pouvoir te dire qu'un traducteur travaille actuellement sur une version française, mais ce n'est pas le cas. D'ailleurs, je ne sais même pas si c'est possible de s'inscrire en tant que traducteur.

Ma seule réponse? Avoir un traducteur à côté de toi (pas Google Trad, on connait tous son efficacité, mais plutôt DeepL ou WordReference) pour pouvoir comprendre tout en lisant. De cette façon, plus de problèmes de compréhension et pour améliorer ton Anglais, c'est le top ahah.

J'espère que j'ai pu aider x)

Yeah, but the problem is that I'd have to write all the dialogue and the chapter goes on for a long time, after a while it's going to get really annoying.So I'm thinking of uninstalling it instead. Too bad because I'm sure it's a very good game.
