Salutet and Environs
In the Beetle Sands, the sands give way to gravel, then to rocks, then fist-sized polished stones. Then, all at once, all the stones are beetles. And they're hungry. That's how it goes in the Beetle Sands.
In the sinkholes, you can find all sorts of things: sulpherous pools useful in summoning spells, nesting swarms of firesnakes, hidden bandit loot, and the bodies of adventurers who came here, just like you, looking for something valuable.
Lookout rock isn't a place you go to look out for things. It's a place where somethings on the lookout for you.
Salutet's a pretty nice town though; friendly people, good food, pleasant markets. You should go there.
