Elder

The Elders of the great forest are the oldest of the Treeman Ancients. The Wood Elves tell that in the time before Chaos, there were hundreds of such beings. Alas, the Elders knew naught of war and, by the time the Daemons were banished, only three Elders remained: Adanhu, who held the gift of prophecy, Durthu strong of heart and limb, and Coeddil the cunning. They were not entirely alone, for many thousands of other Treemen had survived the coming of the Daemons, but they were but striplings of mere centuries, and remembered not the days of the forest's glory.
