Is the Sword Coast big enough to place a few homebrew towns?
I've been a sort of fan of Faerun for years since playing the original Baldur's Gate game as a teen back in the late 90s but I've never really actually played there (my longest running games as a player were an Illusionist in a homebrew world and an Artificer on Krynn). However I'm now looking at starting an online 5.5 edition game and I want to use the Sword Coast.
Baldur's Gate and Waterdeep both seem very cool and I have nostalgic love for Candlekeep from my video game days. That said I like the idea of having a couple of towns in my campaign that are bigger and more important than tiny villages even if they aren't huge cities; it gives me settlements I can personalise and populate and threaten without the PCs being small fish in a big pond. Could I fit in these homebrew settlements somewhere without clashing with canon?
