Worldbuilding Exchange (v3)

Nominations for Worldbuilding Exchange 2026 are now open! Nominate at the tagset here.

You may nominate up to five fandoms. For each fandom, there are five character slots and six "worldbuilding" slots. Because of the limitations of AO3 tag sets, we will be using the "Relationship" field for worldbuilding elements.

Nominate only single characters in the Character field; groups or relationships (/ or &) will be rejected.

Nominate only worldbuilding tags in the Relationship field; groups or relationships (/ or &) will be rejected. All worldbuilding tags should start with the prefix "WB: ".

Fandoms must have at least one worldbuilding tag nominated by the end of nominations, or they will be rejected.
