“Oh,” say those who have played in my campaigns before, “here’s where he’s putting in the rakshasa.”
I'm a big fan of rakshasa, whether you're talking about the tiger-headed sorcerers of D&D or the shape-shifters of Hindu and Buddhist lore. There are a handful of monsters I just really love using, and I try to include them in every campaign. I doubt I'm unique in this, so when building your own hex crawl be sure to keep your favorites in mind.
gnolls (another favorite monster), minotaurs, and maybe unusual merochi families.
Along the river exist small communities and individual freeholds of thri-kreen. These were left behind by the elves when they abandoned this area. South of the city, in the swamps along the coastline of the delta, are hidden villages of turtlefolk. Both avoid the city as much as possible.
In the plains on either side of the river wander clans of wemic. In the hills to the north and east are small clans of hill giants. Both of these prey upon the thri-kreen to keep as slaves for themselves or to sell in the rakshasas' city. Moon beasts may also be involved in this trade.
The broken lands to the west and north are a veritable maze of shattered stones, defiles, ravines, small canyons, and lava tubes. This territory is claimed by a number of minotaur clans. Successfully navigating this maze will lead you to the active volcano at the southernmost tip of our secret plateau. Here, a fortress inhabited by fire giants guards the entrance to the plateau.
What's in the plateau? No idea just yet. But there's still no rush to fill that in. On Friday, will back up, survey what we've done, and discussed how I would actually accomplish this much for normal game I was planning to run.
