Varisia has been destroyed! Runelord Alaznist's
alteration of the past has thrown the frontier nation into chaos, devastated
cities, resurrected demon lords, and worse. The Runelord of Wrath is now primed
to seize control of a ruined realm, so that she can remake it into a New
Thassilon with herself as its furious queen. Only one desperate plan can set
things right-a band of heroes must discover a method to travel back in time and
repair the damage their enemy has wrought on history, but can they make the
sacrifices necessary for victory? This adventure allows the heroes to reach the
absolute height of power, but even the potent options gained at 20th level may
not be enough for the party to survive the furious might of Runelord Alaznist in
her seat of power!
