He was also know to be a powerful Tongue, as was shown in his battles against Morrowind during the Skyrim Conquests. During this time he purportedly destroyed seventeen Chimeri villages and two Dwemeri strongholds, which led the Dunmer to vilify him as "Hoaga, the Mouth of Mud", a vicious demon with necromatic powers.
He attended the coronation of the Emperor Gorieus on the 23rd of Sun's Dawn in 1E 461, along with his father and High King, Kjoric the White. Kjoric later rebelled against the Emperor, but was killed at the Battle of Sungard in 1E 477 or 478. After this, the Moot named Hoag as the new High King.
