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.

Installs
How many people have installed this game, as the storefront reports it. This number is worldwide — unlike the price, the same package answers with the same install count in every market we asked — so it carries no country. Each source below is a different kind of number and they are never drawn on one axis.

Google Play shows “100,000+” on the store page.
Play publishes a precise install counter alongside the rounded step users see on the store page. This is that counter, worldwide, as it stood each day we asked.
Of the eight storefronts we track, only Google Play publishes an install count we can read. Where a store publishes nothing of the kind, this panel shows nothing rather than a zero.
