Hussar
Legend
Because cities on coasts are uncommon...? And the book already does all of that work for the DM in Greyhawk, Eberron, and even Exandra, it's not like the book makes use of FR geography except in broad strokes. There are no keyed regional maps or encounters.
I’m going to disagree here. The module leans hard on FR. Off the top of my head
1. The temple of Ohgma is run by a Shou man.
2. Harpers hire the party in Curious Tale of Wisteria Vale.
3. The Yuan-ti in the Grippli adventure (whose name I totally forget) are very closely tied to FR.
4. Lore of Larue is 100% FR.
5. Sarah of Yellowcrest Manor is plonked into Waterdeep
6. Price of Beauty is tied straight into FR.
Could you rewrite these to put them in a different setting? Sure. Of course you can. But it’s not really a stretch to say that CM is meant to be played in Forgotten Realms.
