Long ago, the exceedingly wealthy Lord Iben Drakhm needed a number of relics retrieved from different locations on the Elemental plane of Air. He carefully selected the most talented adventurers among his subjects for the mission. But only weeks before they set out, it became evident that they were not experienced in dealing with the different environments they would most certainly encounter. So, the mission was postponed, and an expensive training facility was constructed so the adventureres could learn how to tackle a variety of challenges different gases will pose. Thus, no expenses were spared and the Gaseous Grotto was constructed.
