Soul Shifter

In a faraway kingdom, it was discovered one certain kind of magical energy extracted from strange elemental portals that appeared on the land. Obsessed with the power, the ruler of the land, The Monarch, was abused by the magical portals and the creatures that lived in these strange worlds that the portals led. Various researches were made until, one day, everything collapses. A massive explosion happens and the castle of The Monarch was partially destroyed and trapped in an alternated dimension between the realms that the portals gave access. You don't remember your past, who you used to be, or if one day you were something. The only thing you know is that the dungeon summons you, calls you, and you are lured for it. With the ability to use the elemental energy that led the kingdom to ruins fight the monsters that now habit the inner castle and make your way to the last of the floors of the castle.
