You need to fix the Dragon Age: Origins entry bc it's wrong. Arcane is not one of the spell schools. It's the basic class spells/passives, similar to the Warriors and Rogues in the game. The fourth school, after Primal, Spirit, and Creation, is Entropy, with spells like the Misdirection Hex and Curse of Mortality.
Blood Magic is by far my favorite specializations in DA:O and DA2. Just wanted to point out that the picture used for Avernus was actually of Sophia from the Warden's Keep DLC.
