Create a campaign from your User Dashboard by clicking the green "New Campaign" button in the Campaigns panel. The creator becomes the Game Owner and manages the subscription of the campaign.
To start a new campaign, all you need is a name and the game system you are using to play (D&D, Pathfinder, etc). The Game System field does not affect anything within Chronica, but we sometimes use the data to prioritize features for the most popular systems being used.
Your campaign will always start out on the Free (Peasant) tier, and any settings can be changed at any time.
