"place them where you want", they said. But if you want a consistent world, not every placement will make equal sense. Find thoughts and inspiration on where (and why) to put the Raven's purge sites.
Beware:
Spoilers ahead
Although your GM might have an entirely different view on the world. You have been warned, though.
Vond
Vond is most likely the place for the showdown of Raven's Purge. Zytera and Krasylla are here as is the protonexus, which most forces want to see closed. Arvia wants to reconquer the Castle and a free shadowgate pass will open opportunities to start the Bloodmarches Campaign.It should be placed at G40, at the entrance of shadowgate pass and in the direct vicinity of ruined Alderstone.
