The Vapra clan was one of several Gelfling clans that existed on Thra before they were exterminated. A beautiful people, they had white hair and fair skin, and their women had gossamer wings. Experts at camouflage, the Vapra could virtually disappear into their surroundings. The Skesis prized their essence above all others for its restorative effects, which made the Vapra an important resource to the lords of the Castle of the Crystal.
