Deadlands: Heart o' Darkness

The search for the black diamond known as the Heart of Darkness brings the posse to the City of Lost Angels. Rumor has it the gem is being kept in the infamous Rock Island, a prison island that’s nigh on impenetrable (and that’s assuming you can make it through the shark-infested waters of Prosperity Bay). But with a huge payout (and maybe even the fate of the city) on the line, it’s a risk the heroes will just have to take.
