True nature is impossible to escape.
In the conclusion to The Forgotten Gemstone & The Other Castle...
Ule's current male form, Ulmaen, is on the verge of deathmorphing when he realizes what he truly must be-a monster. It explains why his kind, the Xiinisi, keep him imprisoned in the world of Elish. Accepting his fate, Ul decides to become a tree demon, only to discover that being a demon has its consequences. After deathmorphing back into a female-looking Elishian, Ul is captured by two bounty hunters and learns that, due to a prison break at Sondshor Castle, Mithreel, the deadliest of demons, walks free.
During Ul's pursuit of Mithreel, she gains unexpected allies along the way, learns to push beyond the limits of her abilities, but strangest of all, she finds a way out of her own prison. Upon returning to her home world, the realm of Xii, she discovers the Xiinisi are no where to be seen.
As Ul struggles to restore her realm, she is forced to let go of what she thinks she knows about herself and embrace a part of her nature that will assure her place among her kind once and for all.
Join Ul as she pursues a demon and learns she can't escape the call of her true nature, and undergoes her most authentic transformation of all.
