So wait, Elissa steals from her best friend's family (notoriously unstable, politically powerful, rarely challenged). Then she sails west and takes advantage of the next good natured, too-trusting strangers she meets... then goes to the shiftiest port in the world to have the shiftiest mages in the world fix her screw ups... and is surprised when she gets murdered along the way.
I would say being stuck on an island for a couple centuries is getting off rather lightly, but...
Just don't give her anything resembling responsibility over even a dinghy. I'm sure she'll figure out how to screw that up, too. She's real good at that.
Sorry, not sorry, I'm with Rhaella.
