TitanSpire is not so much a campaign, as a setting. A persistent world that will see many campaigns and stories from multiple game systems take place on its lands. These games, and the interactions between the players and myself, will help shape the setting over time.
Retired player characters will become noteable NPCs as well as the focus of history and legends. Uncharted (yet to be fleshed out) areas of the world will be created on an adventure by adventure basis, with the PCs’ interactions helping to shape them.
