The Temple of Eternal Flames is a d20 System scenario for 6th- to 8th-level characters. Part of AEG's Adventure Keep line of short, cheap modules in half-sized format (4-1/4"x11"), it is intended to be run as a single session. From the back cover:

The night is cold and recent adventures have left you without companions. Here, at the Inn of the Green Wind, you seek further glory and adventure. This night however, you find neither. Just a bard composing tales.

He pulls out a pipe and lights it, sending ribbons of smoke to the rafters of the inn. Pictures appear within the smoke, weaving an intricate story of a lamp that flames eternal. As you sit enthralled, your head begins to throb and your body goes numb. Tunnel vision sets in and just before unconsciousness claims you, a woman's voice echoes clearly in your mind. "Now you shall have your vengeance my love."

Waking, you find yourself sitting in a dark, rank, rat infested cell. Strangely, you cannot remember what landed you in this fine predicament. You hear the sharp sounds of metal boots descending a spiral staircase just outside your dungeon cell. The cell door unlocks and bright light streams in, blinding you. A loud voice asks you to step out.

"We have work for you."
