Yirith

One of the most insidious Titans, Yirith is a manic being who seeks nothing more than their own self gratification. This blatant narcissism causes Yirith to hate anything that is not in their image. After Yirith escaped the war, she fled to a remote dimension in the lower dimensions before cocooning herself there. However, Yirith is still one of the few Titans that is active amongst the Cosmic Stack.

The Titan flings her consciousness around the Cosmic Stack before finding a host. After destroying the host’s mind, Yirith begins to possess them. Her avatar begins to undergo a process she calls “the Metamorphosis.” This five part process eventually leads to the host obtaining powers that rival a Material God before passing Yirith’s spirit to the next host as their body degenerates into foaming pink goo. During this process a person can tell the creature is possessed by Yirith from their constant malicious smile.

Each time Yirith goes through the Metamorphosis she improves her phases. Her "life-cycle" centers around absorbing other lifeforms and taking from them their evolutionary advantages. These advantages remain as long as they are useful or do not conflict with other superior advantages. The Titan also takes a creature's memories while possessing their body. This cycle of improvement combined with her ever increasing bank of knowledge and her ability to find new hosts makes Yirith functionally immortal.

As of 715 AR, Yirith’s Metamorphosis has acquired powerful telekinetic abilities and the ability to project illusions. No mortal or Material God has been able to successfully defeat her fifth phase in over two-hundred years. Not even one attack has been able to rid the Evolving Grin’s face of their hideous smile.
