After all this time and effort to get home, Lachwen finds herself at the wrong end of Mirkwood, facing an army of orcs. Her first instinct is to beg, borrow, or buy a boat in Lothlorien and just head up the Anduin, but somehow knowing that all these Galadhrim are here fighting what must eventually be a lost battle against Dol Guldur, home of one of her own people's most dangerous enemies, is making it awfully hard for her to just pack up and hit the road.
In terms of game mechanics, she's L63 and racing to get up to speed for Rise of Isengard, releasing on Tuesday. I suspect that when she hits 64, I'll probably cut and run to Enedwaith so she can grind out the Volume III storyline as far as it goes and do her last bit of levelling at the same time. It depends on how the quest chain starts: she might not receive the starter message for the Prologue until she hits 65, in which case she might just stick with Mirkwood 'til the note arrives. There are deeds she needs in Mirkwood -- Enedwaith, not so much. There she just needs the storyline.
