Costume seller
From AEWiki
Jihama Carana- Everyone going back to the past must be dressed appropriately or they will stand out terribly. You have come to outfit them all perfectly. You are a great scholar of historical costumes.
Alright, actually you know diddlysquat about historical costumes, but academics aren't exactly known for their fashion sense. You can probably sell them all sorts of "historical" crap. You have brought a grab bag of stuff you picked up at thrift stores to fob off on people. Give them a good enough story and they'll buy anything.
