Shaper

Shaper is short for Fleshshaper, an elven caste found among the Illisyr. Shapers are masters of modifying their bodies, or those of others. They understand their bodies on a level that no one else seems to have managed, and they've developed magic which allows them to manipulate it.
Every generation, the Illisyr Shapers make improvements. They alter their members to become stronger and closer to what they view as perfection. Each member of their clans can petition the Shapers to help them grow stronger… and so, with every generation, they grow more powerful.
