The letter is written in elvish

Honored Councilor Maeturorant

I have been told you are the leader of the Spellblades by Nesaine, Hand of the Night. My stay within these walls has not been long, only a few days past I was amongst trees and underneath sky, wandering all of Faerun. The elven warband has taken my interest and I desire membership. When time is available to you, Ernil Du, I would very much like to speak to you. I may be reached at the jocularly, albeit unbecomingly named inn, the Pissing Crone.

May your ways be green and golden
