I love D&D. I've made a bunch of random generators that aren't quite covered with other websites.Dwarf City: create a random dwarf community - from The Book of Dwarves.
Encyclopedia Magica: roll for a random magic item or artifact from the Encyclopedia Magica.
Sphere Generator: creates a crystal sphere with random properties for your D&D campaign's star system.
Star System: create a random star system
Temple of Surrthak: there are many temples around with similiar configurations.
