im not entirely sure if this is the correct place to put this question.

At the moment i am running a 4 player d&d campaign which have taken a trip to underdark (not voluntarily hehehe)

and the biggest challenge i face is getting maps for all kinds of encounters be they random or prepared in advance. so far i have staved off the monotony with maps people have shared on the internet or people sharing map tiles which you can mix and match together to create maps.

what i am wondering is if anyone know of any good underdark/cave system battlemaps which could be used in a d&d game or perhaps a set of tiles which you could mix together to easily creating my own.

part of the reason i started working on my own map and joining this community is because of the difficulty finding maps for this particular setting and keeping them interesting as far as the game is concerned. the issue is largely that creating maps is time consuming work so i have devoted my time in the effort of creating one large map that will signify the end of the underdark section.

any help would be much appreciated
thanks in advance
