Vena is a superviolet drafter and the best friend of Liv Danavis at the Chromeria. She is an artist in both ability and attitude, designing and making her own clothes, many of which are unlike any of the Satrapies' fashions, and often dyes and styles her short hair in creative ways.

After Liv refused to spy on Prism Gavin Guile for Aglaia Crassos, Aglaia used her connections to have Vena's Chromeria sponsorship pulled, which would have forced her to be sent home and live as a servant. Faced with the fact that another refusal would ruin Vena's life, Liv reluctantly agreed.
