The Eternal Boundary is a PLANESCAPE adventure for a party of four to six characters of 1st to 5th levels. Players are introduced to the city of Sigil — the Cage, as some call it. Inside this crossroads to the planes, a sinister plot unfolds, leading the heroes into the most dangerous and desperate part of town — the ramshackle slum known as the Hive. Do your player characters have what it takes to confront the Eternal Boundary — and pass beyond?
