The Nightmare lord has fallen, and we're now ahead of the curve. Bring on Mythic.
Lord Xavius was a powerful user of magic, and the high councilor to Queen Azshara during the time of the War of the Ancients. Since Azshara concealed her magical prowess, Xavius was considered the most powerful Highborne to whom the rest measured their skills. He was later transformed into the first satyr by Sargeras, before ultimately being transformed into the dreaded Nightmare Lord.
