One possible setup for a multi-campaign world you could create 3+ OP campaigns.
OP Campaign Website 1 - Contains all adventures, rules and PC relating to your first campaign, but it would not contain info on the world. That would be linked to OP Campaign Website 2
OP Campaign Website 2 - Contains World info, religion, cities, countries, possibly NPCs, possibly noteable adventure summaries, basically anything that you'd want to be shared with future campaigns.
OP Campaign Website 3 - Contains all adventures, rules and PC relating to your second campaign, but it would not contain info on the world. Where needed to would be linked to OP Campaign Website 2
