The VOIDRUNNER'S CODEX is coming! Explore new worlds, fight oppressive empires, fend off fearsome aliens, and wield deadly psionics with this comprehensive boxed set expansion for 5E and A5E!
The Keep has a store in Brunswick as well as one in South Portland. I haven't been to either in a few years, but I do remember that they shrink wrap EVERYTHING which was a big turn-off for me.
While I don't know of any game stores as such, the Bookland in Cook's Corner has a fair selection of D&D stuff; not really sure how current it is, though. When I was there this weekend, my attention was mostly centered on the Collosal Red "mini".
I was able to find a good book at the Keep for 50% off, though it was shrinkwrapped. Thanks for the tips (we didn't have time to check out the Cook's Corner bookstore).
