A Study in Collaborative World Building

Recently, our gaming group got together to start planning a new D&D (5e) campaign.

My gaming group is currently composed of a core set of players that have been with me since 1999: Math, Yan and Franky. Three or so years ago, my friend Chantal joined us. And last year, my son Nico (remember him?), now 14, has become a permanent player.

We made characters together and ended up with the following.

  • Yan: A cleric of the unnamable God of War, ex-child soldier, ex-gladiator
  • Math: A fighter and brother to the cleric. Also ex-child soldiers and ex-gladiator
  • Franky: A Witch Hunter hunting evil supernatural creatures (and selling their organs on the Black Market)
  • Chantal: A path-seeking motorcycle-riding “Steam” Monk
  • Nico: An outworldy Warlock, with a serious burden

The next session,  I went back into my world-building tools and applied methods I talked about in my Index Card Codex series (Part 1, Part 2).

The following represents what was written on five cards once I was done.

With these, I’ll start building campaign-specific index card decks, namely:

  • A City Deck for the campaign’s early adventures.
  • Event Decks for the city, based on themes players have asked for.

As the campaign progresses, I’ll build more decks and change cards as the actions of players shape the world.

I’m excited!

Steam monks!
