I'm trying to adapt the sea route taken in Sea Wyvern's Wake to the Eberron campaign setting. My plan is to take the PCs south along the coast of Q'barra and into the Dragonreach, where I plan on placing the Isle of Dread. I'll be replacing the Olmans with a primitive clan of Seren barbarians. The barbarians were abandonded by their dragon leaders when they allowed Thanaclan to be destroyed.
Anyways, I digress. My question is this: Where can I get a single detailed, coherent map of the east coast of Khorvaire?
