Nah. Elisif needs to find a relatively place where she can take stock, hone her skills, and remain off the grid until she's ready to move. Also, a place where the Brotherhood isn't likely to look, with people far enough removed from the /currently acknowledged/ troubles that they won't second guess (much) a wealthy but at the moment still green warrior so long as she helps out.

Jorvasker is too public and Sky Haven Temple isn't available yet. So I am of course speaking of Fort Dawngaurd. Get some use out of Dawnbreaker. And show me the DB operative with the balls to risk getting in range of Isran, who himself would probably happy as hell to have Jarl Elisif helping the cause, and perfectly willing to grant her some cover.

That and Serana would be a just outright *mean* suckerpunch for Elisif to pull on her enemies.
