Subterranean Entrances in Chagrinspire

Played Gunderholfen solo up to 4th level sub levels. Had a few close near TPKs, lost a follower and blew 20% of all cash made on a raise dead for them. Blew every potion. Currently fighting undead which is a bit tedious now cleric turns used up. Cleric also has diseases but has a scroll - waiting until really need to use scroll as might face more undead that cause this. AC of cleric and fighter have helped them do ok. Helping to test new rule mods before next game and new character sheets. Currently running Marvel and it needs very little prep with tables i made this year and player-driven choices. Playing Ravenloft 5th ed and long time since i was a cleric. Feels like i can do cleric and fighter and wizard stuff well by my old-school wired brain. 

------------------------------------------ 

There are dirty holes all over the wastelands. This is to help generate on the fly. Some might be where monsters they meet as encounters call home. Some might be dungeons or underground transit tunnels. 

I will start on the Chagrinspire region map soon. The innermost defence ring around the dark spire has ruins of cities mostly drowned in mud or warped by Chaos hoping to subvert the Black Sphere mechanisms. They will be slow to find worthwhile undamaged goods and have to weigh it up with the risk of encountering mutants and creatures living in the ruins who hate outsiders. Once im satisfied with this outer region stuff I will work on the Dungeon Proper. All this started from a dungeon doodle and the urge to make a a exrta grimy filthy post-apocalypse fantasy world.

Will be working on post about the walls of the star fort around chagrinspire with vast walls with huge cannons and signs of past damage.
