The fountains of Dirge were two fountains located in the inner and outer courtyards of the Temple of Dirge. They were one of the sources of the Water Dragon's power and as such they were protected by the Spirit Monks. If the fountains were tainted with human blood, the seals on the fountains were shatter and thus weaken the Water Dragon. Removing the seal would have the same effect. If the fountains were defiled, they could be restored by removing the blood and replacing their seals. Spoiler warning: Plot and/or ending details follow.
