Are Holds the only places there are guards? Specifically, are there guards at crafthalls and weyrs?
It's been a while since I read the books, but don't Weyrs do watch dragon/riders in lieu of guards? I could be wrong though. It HAS been a while since I read the books. I should reread them. lol
I can't remember anything about Halls at all, though. lol
As far as Triad posting, we've never written guards anywhere else besides the Holds that I remember.
The Weyr does do watchdragons who stand sentry. As far as our Weyrs go, most of them are only accessible by dragon for the most part so there aren't many security risks. IE: Dragonsfall is up in the mts, DCW is right on the ocean, and RBW is right on the ocean (there is a road to JHH) and can be gotten to by boat.
Halls..they may have a watchwher possibly like the Holds do but we've never played that out either since they're usually near the Holds and so use their security for the most part if it's needed.
