The Empress?

Once the tarot embodiment of The Empress, her realm was in grave danger, it was going to be completely destroyed. The Sun, The Moon, and The Hermit all had an idea that The Magician had a hand in helping to try to combine everyone into one being that can withstand the destruction. But it failed. They all fused into The Empress to create a new tarot card that's never existed before. The Loser. The Loser is an emotional card that expresses extreme guilt and failure to fix problems. She has been emotionally unstable due to losing her whole realm and all of her people being fused into her. Now she wanders, trying to find peace somewhere, somehow. She can read your future with tarots if she wanted to, but she can also use the tarots to summon attacks when she is in combat.
