|Race||twilight drake (Dragonkin)|
Tenebron is a summoned twilight drake in the Obsidian Sanctum, appearing in the fight with Sartharion.
If left alive, she will apply her aura, Power of Tenebron, to the entire raid as long as she is alive, increasing Shadow damage taken by 100%.
Tenebron should be tanked facing away from the raid.
Periodically, Tenebron opens a portal to the Twilight and begins hatching eggs, which spawn whelplings if the raid does not enter the portal and kill the eggs. The raid should leave the portal alone and keep nuking Tenebron the entire time. It is almost inevitable that one wave of whelps will spawn from the portal, and depending on the raid DPS, possibly two waves. When that happens, have an offtank pick up the whelp adds. Once Tenebron is dead, AoE the whelps.
Her name is likely taken from the word tenebrae, which is Latin for "shadow".
