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.

This is legitimately one of the best games I've ever played. The story is amazing, really captivity and even made me cry at one point. The art is phenomenal! Hauntingly beautiful and character design is incredibly peak. The gameplay fantastic, only beaten by slay the spire I'd say. Pulls are generous, been playing for free and just did my 1000th pull due to how many yah can earn for free via playing. The sound design is PREFECT! Perfectly capturing the tone, mood and amplifier it. 10/10

very fun, I don't need to clear main story to level up my characters like other games. instead, I only need to clear things that are intended for higher leveled players. it's not so hard once you level up your main 4 characters. easy to get the wheel of destinies (weapon) and enlightens (copies) of the characters. pity is 30 and you'll get the limited SSR guaranteed after losing two times. very generous with silvers and pulls. standard characters are also very good for beginners.

Re-uploaded my comment on the game. It is great, the gameplay, the dark lore, everything is great. But after 40 hours in this game i got an problem related to the optimization. I believe my device (Samsung A36, 6 ram, one ui 8.5) would run better this game. I tried to lower the settings but the game always feels it would crash every moment. Despite my good wifi, it still downloads slowly. That's my problem, the optimization. Thanks you and keep up the good work.
