|Race||Merciless one (Aberration)|
Xalzaix is a merciless one that belonged to the C'Thrax known as Mythrax the Unraveler. Defeated by the snake loa Sethraliss, Mythrax was resurrected millennia later during the Fourth War. Channeling his power into Xalzaix, the faceless general destroyed the Great Seal at the heart of the great pyramid of Dazar'alor. He used it once more when confronted in Uldir, but was killed by brave adventurers.
