About this game

Keeper of Secrets, congratulations on entering Mythag University.

This world is dying.

Hundreds of years ago, Dissolution came with no signs. Life, consciousness, memories...All the existence that humans once gave meaning to were erased by Dissolution.

Yet people were kept in the dark.
Confronted with this hidden and indescribable disaster, Mythag University, as one of the few who is well aware of this fact, is determined to fight against this vast crisis by waking up the power that shares the same source of the disaster and connecting the humanoid weapons that are on the edge of insanity.

If everything is bound to be forgotten, are you willing to testify that the world has once existed? Will you carry the secret on your back and walk on by?
In the witness of the gravestone, may the Silver Key guide your way.

Welcome aboard, Keeper of Secrets.

In this misty British-style world, you shall carry the secret of the times for the sake of all life.
In the crisis of Dissolution, grace and power will be with you everywhere you go.
Arrange your team, and wake the ones who share the same source of disasters.
Go through Rougelite game levels, and uncover the unspeakable truth with your strategy.
Experience this grand story with multiple chapters. You will find the trueness in this broken world.

Downloaded this app only 2 days ago and it is honestly one of the most fun games iv'e played in a while! The animation and art is CLEAN 🤌🏾, voice acting is AMAZING, the story PULLS on my heart strings, and the sound track is truly BEAUTIFUL. To put the cherry on top it's one of my favorite strategy type games, card based (I did not look at all the provided imagaes before downloading so it was a pleasant surprise). Anyone who loves strategy games please give this a try, it is so fun!!!

I just started actually playing the game after having had it installed on my phone forever now. and I will say, I regret not starting it sooner because so far it's already climbed into my top Mobile strategy games.. and the fighting actually has more strategic gameplay and abilities to explore than most similar games. plus the artwork is not only as beautiful as I expected but ab ok e and beyond with amazing character detail. but I just barely started so I may end up editing my review.🥹😳🫣

I've sunk over 70 hours into this game just THIS month and That's just on my phone! I'm definitely hooked. The gameplay is great, so many team comps and strategies to work with. The art is also great, the character designs are cool and elegant and the boss designs *chef's kiss* very Eldritch horror. OH but the story, the story is amazing I can't recommend this game enough.
