From publisher blurb:
Using the SPAGS system (the solo-player, party-based Pathfinder game system)
Take your Avalon Quests to new heights with this great low-level setting of adventures and fun.
It's all here: the inns, the monsters, the treasures, the secrets, and — most of all — the story!
Avalon Quests will generate a fully realized campaign world complete with wilderness travel, set dungeons, randomized combat, special encounters, and a story—everything you need for a full campaign of Pathfinder, all while playing solo.
You must have a copy of Avalon Quest and the first Adventure to use this product.
