She is rather easy to find, sitting at a large desk writing upon a tablet as she is counting trinkets and thingamabobs. Weapons Grade Thingamobobs.
Her name is Gemma, and she looks up at you with a smile.
Well hello again Cornelius. And greetings and well met newcomer! My name is Gemma, perveyor of the finest magical items and venditior to the most famed Verditius magi of the Order. And I can guarantee that all items are of legitimate origin and can provide certification. Just ask Cornelius. She smirks. If you need something customized, just describe what you are in need of and I can put you in contact with the right magus.
So, how may I help you?
