Mines of the Eye

Adventure description from front page "Deep below the Abbor-Alz the duergar are stirring. Rumours of a fell compact between the duergar's mysterious leader, a being known only as "Father Eye" and the perfidious Rary, monarch of the Bright Lands are rife. What evil purpose is served by this alliance is unknown, but assuredly it serves some goal in Rary's greater design. The paladin Karistyne has determined that Rary's scheme must be stymied and so the call has gone out for doughty adventurers to eradicate this growing threat. An adventure for characters of Average Party Levels 2 through 16."
