Well with a lack of clarification, and a poor choice in unlock reputation on Blizzard's part, we can only assume that right now Void Elves = Kingdom of Stormwind as far as a specific Alliance rep faction is concerned. Ideally there would be a specific rep faction for those who study in Telogrus such as "Acolytes of Telogrus" or some such. Maybe down the road Blizzard will add such a faction.
