If you're looking for an oriental-themed world with a nasty twist, this is it. In a war between two celestials, an object of immense magical power has fallen, and not in a good way. Leaking magical energies, not only do archmagi want the power, but it has mutated and devasted the entire land -- and awakened another god, as well. Horrible creatures have arisin, civilization has broken down, and terrible magic seeps over the countryside. Refugees... mutated creatures... magical devastation... pockets of oriental and occidental city-states... the occasional sanctuary... the followers of a snakelike demigoddess... Qelong is packed with adventure seeds for a GM to develop.
However, that may be the problem. For GMs looking for low-prep adventures, Qelong isn't it. Most of material is presented in the conventional "two lines of description and a big stat block" format, with random encounter tables for wilderness areas. With many of the scenarios involving humans and other intelligent creatures, the GM will have to develop a situation which can't be solved with combat alone. The ideas in this setting are fantastic, but require a fair amount of work to develop.
