I'm a firm believer that OD&D and 1E are the best versions because the rules have a mystical quality to them. In addition, since I run a medieval western campaign (always have, always will) I stick to the base classes. I wanted to include monks in my campaign, so I created the Monks of the White Lotus.
This is the finished recreation of the Temple of the White Lotus, devoted to study and training, and includes the largest fountain/reflecting pool that I've ever created. The monks supplement their temple's coffers beyond donations by selling their famed lotus at local events, and are a source for rarer varieties of the popular flower.
