From the frontpage of the module:
The Tenh has been shattered by the might of armies, decimated by the voracity of Ether creatures, and subjugated to the powers of the Pale. Duke Labahlah now seeks to lead his land into a new era of greatness, but a formidable foe arising in Stonehold could dash his hopes. Can you secure the realm long enough to grant it a chance to recover? A one-round Core adventure set in the Duchy of Tenh for characters level 8 - 15 (APLs 10 - 14) who remember that the enemy of my enemy might be my friend. The final part of "Legacy of Life".
