Keeper | World of Warcraft: Redux
Keepers are the sons of the demigod Cenarius and, unlikely their sister nymphs, they tend to be more uniform in appearance. Keepers of the Grove are the most common among them, but Keepers of the Glade, Valley, Prairie, and Reef exist as well. Most of them resemble their father, but some may have traits from the places they protect, like grape vines or barnacles.
Unlike nymphs, keepers are bound to the groves and glades they protect, rather than being tied to a specific tree. They are reborn at their homes if they are destroyed or damaged in some way, and their fates are tied to their homes, which act as extensions of their own body.
All Keepers start their lives as nymphs. When a grove becomes strong enough that it needs a Keeper to protect it, a powerful dryad will bind herself to it and begin to transform into a Keeper. Usually this means taking on a more masculine appearance.
