RPG Challenge, Day 11
Favorite Adventure You’ve Run
That’d probably be The War of the World Oak.
Very short form. I ran a heavily-modified 2e D&D game for about a decade. One of the major story threads was that an ancient evil had, generations before, tapped the power of the World Oak, one of the primal sources of life and a prison for a powerful force for death and decay. That ancient evil had created a siphon for the World oak’s power to go to a group of its servants who gained vast nature-controlling powers.
The servants survived the fall of the ancient evil, and went on to become druids: powerful defenders of nature and greenery – who in time forgot that their powers were stolen from the World Oak. And who spread. And grew. And became a religion with no need for gods because they had a separate divine source of power. And eventually (over centuries) were drawing enough power that the World Oak began to die.
If it died, a massive force for death and decay would be released. So the PCs from about 4 different games all played on the same campaign world, with different (but overlapping) players and different levels and even different themes, had to find the World Oak, stop the cult trying to kill it (to release its prisoner), and do so while knowing that success would require them to cut off all of druidkind from the core source of their power.
It was one of about 3 major plot arcs in that world, and at the climax I had a weekend-long game/party with a massive battle that included a built-up 3D set of two roots of the World Oak, where the final battle took place.
