Annekke Crag-Jumper is Bethesda's attempt at throwing Charlize Theron into Darkwater Crossing to see if you'd notice. After first talking with her, she won't reveal her quest. She may have learned this tactic from Roggi Knot-Beard, who also withholds his quest, or she's just into playing hard-to-get.
Though a stunning vision
to be sure, she does have the exact same stats as fellow Darkwater Pass citizen, Derkeethus. That means if things don't work out with Annekke, you still have shot with the Argonian miner down the way.
