Vaarsuvius is an ambiguously gendered high elf and a member of The Order of the Stick. After studying for nearly a century, Vaarsuvius has decided to become an adventurer to expand his/her knowledge. Vaarsuvius is sometimes referred to as V, and has a friendship with Haley Starshine. Belkar Bitterleaf is one of Vaarsuvius's rivals.

In game terms Vaarsuvius is a wizard who specialises in evocation and enchantment spells, with Evocation as his/her specialty. His/her barred schools are conjuration (revealed in OotS Comic #340) and necromancy (never stated but can be inferred from information - Vaarsuvius has used at least one spell from each school except for conjuration and necromancy). His/her familiar is a raven, which Vaarsuvius never got around to naming, but Haley Starshine named Blackwing. Vaarsuvius constantly forgets that Blackwing exists, even forgetting its дана name (although this has changed in later comics).
