Back in July 2013 Wizard101 introduced a sidequest NPC in Dragonspyre along with Aquila. Behold, the Loremaster!
Not only does she have an amazingly cool cyborg ghost look (Cyborg ghosts are the best!) and hangs out in the library of Dragonspyre, she has a loot table that coughs up rare spells from all the hoard packs . . . even the most recent Krampus spell (first hand knowledge on that one! :))
And because she's an alternative to spending money on packs to get a rare spell, she's awesome.
