Unbelievably Fancy Ostrich
This is much more interesting to me than Astrazalian. I'll have to write about it more later when I'm not on my phone.VoidDrifter has just summarized an interesting Dragon article in their Let's Read of Setting Lore for the Nentir Vale. It's on Rahesh, a city of necromancers:
In the article, Rahesh is destroyed by volcanic activity, but I'm intrigued. This could be an interesting seed for the game. If Rahesh still exists, but has been isolationistic and not nearly as expansionistic as described above, I could see the PC party being a group of envoys from this city reaching out into the planar community.
