Summoner Nolric

Summoner Nolric is a high elf warlock trainer located in the Silver Enclave in the mage city of Dalaran.

He was present in the city when it relocated above Deadwind Pass but did not offer his training services as he had to remain alert for any danger to Dalaran's visitors.

Speculation

 * The fact that he's a high elf and also a warlock trainer is somewhat unheard of. There is almost no lore about elven warlocks prior to Blood Mages that, arguably, use warlock-like magics, and later blood elves allied with Illidan. Although it's known that high elves did have vast knowledge about demons, there is no lore against or in favor of some becoming warlocks. Given how warlocks are found in other societies, it doesn't exclude high elves. Even if Summoner Nolric is a special case and decided to become a warlock by himself, it doesn't explain why he still has blue eyes. However, the appearance could most likely be game mechanics.
