The Sinwell was considered to be the opposite, with its dark waters supposedly containing all the dark deeds that the people had cast off and forgiven. A day’s walk from the main settlement, the Sinwell was not guarded or barred, as every member of the community was invited to cast their sins into it at any time. While this often involved simple prayers, it also could take on a more literal form. Many objects were hurled into the Sinwell, and putting an object in dispute into the well, and therefore out of reach of all, was an accepted method of settling disputes. It goes without saying, too, that the waters of the Sinwell were strictly taboo and were never touched or imbibed.
Eventually, the communities in the area were scattered and destroyed by invaders, with the Sunwell’s hidden location being taken to the grave. This left the invaders with no source of potable water, and they therefore took advantage of the Sinwell, lowering buckets into it. This was despite being explicitly warned by both captives and their own guides.
Modern-day analysis of the Sinwell has determined that, other than large amounts of dissolved minerals and a large number of objects, the water is completely free and clear of any toxins or other poisons. The invaders, however, perished almost to a man, leaving the area depopulated as survivors from both sides fled. Until the last member of the extinguished community died nearly 100 years later–taking the location of the Sunwell with her–it was maintained that it was not any poison, but rather centuries of unfiltered sin which had slain the invaders.
