Despite being in Terran, I regularly correspond and interact with people in Summerdale, Morek, LE, and Astrum. I think you underestimate the isolation on Dwilight. Join some guilds and a big religion (VE or SA).
I personally love how Dwilight feels like multiple continents in one continent.
In my opinion the size of Dwilight makes it the perfect continent for just this reason, it recreates that medieval feeling of massive separation between realms. I would actually like to see the other maps either removed or updated to the same sort of expanse. A Dwilight style map without the massive rogue forces would be interesting I think.
