Escher Belasco is a vampire spawn and a consort of Strahd von Zarovich. Originally from the town of Barovia, he now resides in Castle Ravenloft in the nation of Barovia.
Prior to becoming a vampire, Escher was a close friend of the wereraven Fyodor Martikov. Fyodor says that the Keepers of the Feather "failed to save" Escher from Strahd. "He always dreamed of better things, better than this place. He was always smiling, even at the darkest times. I promised him I would protect him, but I failed. He tried to help us fight against Strahd, but he was taken, and it was a long time before I saw him again. When I did... He had changed. I do not know him anymore." -Fyodor Martikov
