To whomever it might concern.
Señor,
in the course of an exploration that hath passed yesterday, information of potential interest to thy organisation as well as to all the citizens of Sanctuary beseeching their safety hath been discovered. I solicit a fragment of thy precious time to hear the information and to aid all of us in the noble quest. Should we encounter success, the defences of Sanctuary shall become even more formidable, and the terrible risks that plague the environs potentially reduced.
If thou findest thyself inclined to accept, I can be reached at the Rock Bottom Tavern.
Thine, faithfully
Eireamhon ap-Thaenyeth
