Welcome Garrison! Glad you are enjoying EfU!!
Yeah, I should make a larger map with some map notes or something so you all can print it out for future use, but trust me, you'll learn every nook of the area soon.
(Although I am expanding Waterdeep to 4 parts, THAT may really need a print out map, as it's gonna have lots of shops).
I plan on expanding Skullport after I finish with levels 16-18 of Undermountain. It'll be called "Skullport - The Warrens" and will also house an arena to fight NPC's for items/treasure. Depending on scripting, I can spawn in an NPC fighter of the same power as the player level--to keep the fight even, and winning will give you some nice stuff!
