Alric was the leader of the west and the Nine during the Great War against Balor and the Fallen Lords. During the early years of the war, during his adolescence, he and the royal family narrowly escaped the razing of Covenant via a secret passage, a passage that would be used again by the Legion many years after.
Alric assumed leadership of the west when he came of age, or when his father (the king) died. He had also gone through the initiation rites of the Avatara archmages and joined their ranks, becoming a fighter of great power.
He led the west to the best of his ability, often leading from the front in some cases.
During the final phases of the war, Alric was captured by The Deceiver in the east and was interrogated by Balor himself. He had also learned of Balor's weakness, in which he bound all of the fallen to himself to ensure their obedience. This meant that if Balor was killed, all of the Fallen would be powerless. He was rescued by the Five Companions and, after dueling and killing the shade Sinis, Alric teleported himself and the remaining Companions back to the west.
He is skilled in the use of magic and uses many Dispersal Dreams throughout the games. he is also a skilled combatant with a sword without the use of magic. Beyond any of this however, is that he bore the Ibis Crown. A powerful artifact--unagreeably the most powerful artifact of the Myth world besides Balmung, both he used against Soulblighter.
Alric, being the greatest of the Nine, boasted many powers--including teleportation. He is renowned for using Dispersal Dreams, but this is a common spell among the avatara and should not be considered his greatest asset. Alric also had the ability to create fiery explosions from the ground--whether this was a magical ability that he knew or from the Ibis Crown is unknown.
Alric's other great power is his knowledge and ability to pick up any Myth World Artifact, and use it to its full potential. Among the many artifacts outside of Balamung and the Ibis Crown, he bore one of five Elbis Stones. He didn't use this in the Myth 2 game, but strategically, he could have still made use of it.
Alric is also very resistant to lightning and moves like a warrior despite his old age.
The Ibis Crown boasts numerous powers as listed from GURPS. With the Ibis Crown, Alric can cast spells of Fear, Bravery, Berserker, Daze, Sleep, Peacefull Sleep, Madness, Nightmare, Loyalty, Charm, Emotion Control, or Suggestion. In other words he can Bind Dream like Mydred or make his melee abilities that much better.
It is stated that Mazzarin was the greatest of the archmages to ever live in the four ages--but Alric could have eventually surpassed him.
As an Avatara during the Great War, Alric could haste himself, create a magical shield around himself and others, Alric could also unleash a green bouncing ball of energy, could cast the spell "vengeance," and he could also cast a spell that upgraded his melee ability in a kingly way (Aura of Command).
