Chess is a low-ranking vampire serving as the aide of Crowley Eusford, the 13th progenitor. She has a ditzy and whimsical attitude which foils the mature nature of Crowley's other female companion, Horn Skuld. She is capable in battle but struggles to control her thirst, often killing her prey by mistake. Chess is interested in human culture and activities. She's somewhat simple minded, which aggravates her when Horn one-ups her ideas in front of Crowley.
