Dungeon 153 was the third issue published solely via the web after Wizards of the Coast assumed control of the magazine from Paizo. It contained six articles released online in that month:
-Caravan of Glauu the Seer, a Side Trek adventure for 6th level PCs (available by pdf)
-Prisoner of the Castle Perilous, an adventure for 18th level PCs (available by pdf)
-Touch of Madness, an adventure for 10th level PCs and the first adventure in The Tear of Ioun series (available by pdf)
-Witching Season, an adventure for 6th level PCs (available by pdf)
-Two Dungeoncraft articles, released only as HTML pages
The articles were never collected into a single document. Some are still available online.
