[Tulya]

While the elves we've seen do seem to tend towards being efficient to the extant of appearing cold, Niu does have possible value beyond a single sending. Sending can convey a great deal of information in 25 words, used well, but it still requires sacrificing significant information.

Even so, it would be understandable to leave her to find her own way. Niu is an experienced Fighter/Rogue. She's been fighting as a part of the resistance for a great deal of time, now, in adventuring terms. She should be able to evade encounters she can't handle, and avoid perils more naive NPCs would fall to.
