Sir Armen Cosgrove, retired Knight of the Lance and nobleman of the Theocracy of the Lance, has hired you to locate and explore a here-to-for unknown tomb. After signing a contract, the PCs follow the directions of Sir Cosgrove, sailing from Arvale City to Freeport, then to a suitable location off the coast of the Achsfel Wastes. Using a crude map, the PCs must trek through the plains to the Mountain of the Fifth Prince and locate the landmarks which lead to the lost tomb. Explore the tomb, recover the item which Sir Cosgrove desires, and return to Arvale City alive.
