Aldhaven, that metropolis in which a hundred adventure have led to a thousand stories and countless more would be adventurers have ended their final chapter. Aldhaven has been an ongoing campaign setting in one form or another since 2001 but grew to its largest in the 2010s with an online play-by-post game with over more than 70 active players and half dozen game masters all coordinating to create one massive shared story.
Over time, the city and setting of Aldhaven grew by leaps and bounds, expanded in breadth and depth, intimately shaped by the actions and creativity of both the players and the GMs. In order to better maintain a cohesive experience, and to keep from needing to repeat these same rules in multiple different locations, this site was created to host the compiled rules, rulings, variants, homebrew, answers to various questions, and other rules oddities of the Aldhaven setting.
We are not advocating that this be the standard rules set for all games, but these rules have worked well in Aldhaven and will be the official rules set for all official Aldhaven games.
