My buddy Nils over at Enderra.com is the Gandalf to my Frodo. He drags me from my hole and opens up whole new worlds through his experience and wisdom. I cannot thank him enough. He's been a patient mentor, chat buddy, and a great sounding board for new ideas (and sometimes rehashing old ones).
His latest finds/contributions are these:
Yawning Portal Maps 1
Yawning Portal Maps 2
You really really need to check it out. I'm floored by the number and posts since March. I cannot imagine having the drive and dedication to pull off a blog like Yawningportal. Tom's experience and know how goes back decades, and it absolutely shows. His passion and penchant for D&D obviously shows, but it's equally impressive how versed he is in other games and design as well. The man makes his own miniatures and settings for gods' sake!
