An ancient dwarven City Under The Mountain lies in ruins, and the dwarves are determined to recover the lost treasure. Eight dwarven-run mining companies are ready to finance the project. You represent a party of dwarf prospectors that enjoy digging and would not mind getting rich in the process. On each of your turns you will dig on behalf of one of the mining companies by placing tokens on a modular board. You will receive rewards for everything you may find. You will be going through tunnels, recruiting new dwarves, finding gold and opening treasure chests. You will also have a chance to invest in these companies on a stock market and get a share of their profits.
