Each player run city will have a stable of 3 heroes at any given time. If a hero retires or dies, the city must give either 1/4 of its coffers or 5,000 gold to their family, whichever is lower. The heroes rotate through missions. If a hero is neglected, he may choose to retire at DM discretion. Items equipped to or owned by heroes are considered soulbound and may not be traded to other heroes.
Heroes will level up as the city levels up and new resources become available to them. Otherwise, heroes will function much as traditional PCs do.
