It's all about the Written Word. Networking

I awoke, suddenly finding myself in a strange place, and lo and behold, this scroll had been placed beside me, awash with power, and, forsooth I cast Identify. It was henceforth revealed to be a wondrous magic item, a Scroll of Networking! What working with nets has to do with communication, I know not, but apparently it will let me speak with anyone else holding a similar scroll, no matter the distance!

I mean, it's a wondrous item, so how many of them there are I don't know, but it's really really neat! I mean. Ahem. Its rarity knows no bounds, and... and... yeah, I'm losing that one.

Anyway! Yes. I am Callyn, of the Ashtanic City Guard. I was lately travelling with my dear companions. If anyone sees a few elves or a half-orc or a bugbear, I beg you, please tell me! Oh, the bugbear may be under a spell of Disguise Self, so if you see a human, just poke about a foot to one side of him, and if you feel a nice, muscular, furry arm, that's him.

Ugh, I can't believe that damnable necromancer escaped again! And what did he do this time? Not that I'm complaining about being out of yet another sewer, but where's the rest of my party? And where am I, for that matter?
