From the Introduction: Burrowing Bounties is a standalone encounter designed for five 2nd to 4th level adventurers. A mine infested with kruthik has caught the eye of the industrious Forever Endeavor Trading Company, who is looking to hire any adventurers brave enough to sign a contract and exterminate the pests below. The PCs will face off against mutant kruthik, strange eggs, and the mysterious forces of cadbarium gems—all in the name of a little profit.
