from page 3 of the scenario
The Pathfinders descend deeper into the ruins of Bonekeep, a centuries-old siege fortress.
The deeper dungeons of Bonekeep hold even deadlier threats than the first two levels, yet even they cannot compare to the terrible revelations of the tower's true purpose. A level 5-9 adventure.
Ruins of Bonekeep is a series of special events for the
Pathfinder Society Organized Play campaign designed by
Jason Bulmahn, Lead Designer of the Pathfinder Roleplaying
Game. Level Three: The Wakening Tomb is the third and final
event in the series. This event is designed for six characters
from 5th to 9th level.
At present this adventure is only available for play at conventions. The plan is to release it publicly down the line, but exactly when is still being decided.
