A shimmering portal materializes in front of you. A wizened old man with a wild beard, a wide-brimmed pointy hat, and a long flowing robe steps out.
'Tis I, Athanasius Spagnum! Keeper of a thousand mysteries, delver of the Understar, master of the Codex of Zbornt! I have come from my home realm to yours, in hopes of conducting research on the inhabitants of this world. From time to time, hopefully daily, I shall deliver my observations to you via messenger crow, orb transmission, or blogging platform, whichever you find most convenient.
Toodle-oo for now, and may the Astral Turbo-Dragon smile with favor upon you!
The man leaps back into the portal, dropping his hat in the process. His arm pops back out from the portal to grab it, barely retrieving it before the portal closes.
