Thyrm is the final boss you'll face in Thrymheim, an inverted ice pyramid dungeon in ALfheim Online. He's also the key to completing The Holy Sword of the Ice Palace quest. What makes him stand out compared to New Aincrad's bosses is that his three massive health bars are actually visible to players during the fight—something that lets you track your progress instead of just guessing when he's about to go down.
