A base of the Corrupted Ancients filled with satyrs.
A base filled with skeletons.
The Corrupted Ancients were a group of satyrs, corrupted ancients, corrupted treants and skeletons in service of the Burning Legion commanded by the dreadlord Tichondrius.
They were charged with preventing the night elves from awakening the Druids of the Talon in Winterspring but were slain and the druids were awoken.
The main bulk of the Corrupted Ancients was with their master in Felwood where they were ultimately destroyed by the recently freed Illidan Stormrage.
