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 game is great, from characters to artstyle to music, this game is fantastic. At the moment, the game does not suffer from power creep, that I can tell, and the pulling system is quite generous with most characters being able to be pulled or granted using special items. Now the obvious part, the game from what I can tell is a relatively small group and lacks a real translation team and it really shows in the story. Many times you will see "he" when referring to a female character. othrws gr8

The characters, artstyle, and UI are all very beautiful and I like how they have a card turn-based game. However, the gameplay can be too lengthy due to the additional interface where you travel, going from one tile to another. It can be very annoying especially if you're a casual player who plays in their free time because it feels like FOREVER going through some story stages. Even though it's f2p friendly, I can't get by the fact that they use ChatGpt to translate game text. They're not good.

I love this game. The character designs are gorgeous. It's a card game that requires you to be strategic. This is certainly not an idle game because of the time it requires for you to understand your deck. If you are someone who likes to be "involved" in the game, who likes to strategies then check the game out. The moody atmosphere, the eerie background, and the haunting music add to the overall charm of the game. PS: Starting the game is quite challenging, but hang in there^^ it's worth it.
