This adventure started with a casual decision I made in the middle of writing the Grail Quest adventure. In the crystal cavern hidden behind the Grail Tower (aka The Tower of the Lovelorn Knight), there was a Hall of Many Doors, with a pit at the end. On a whim, I decided to have you find a set of ancient bones, and strange cards bearing names like "James St. John" and "Isaac MacAllister". It was intended as just a way of making you, as players, go "WTF?!?".

Having defeated Tynillios and his collection of the party's alter-egos, the party debated about how long to wait before returning to Earth. The Gatestone pointed to a weathered flagstone in the center of the tower's floor, and Earth's was the only facet still glowing green on the Gatestone. After healing up as best they could without an overnight rest, they decided there wasn't likely to be any danger waiting for them back on Earth, now that Twynillios was out of the picture. Placing the Gatestone on the flagstone, they pressed the facet for Earth, and felt the familiar stretching sensation.

The party took an extended rest after defeating the SpellWeaver, and then prepared to leave. They were reluctant to leave all that valuable-looking loot behind, but could find no way to separate any item from the rest of the hoard. The Gatestone only had two facets left untouched: the one for Earth, and one more unknown universe. Pressing that facet, they felt the now-familiar stretching sensation as they were transported across dimensions.

Having survived their encounter with the gremlins, the party paused to catch their breath and bind their wounds. They searched the room, but found nothing magical (or almost anything that wasn't broken, shredded, or befouled by the gremlins). That just left the doors in the far corner of the room, so arranging themselves, they pushed them open.
