Scenario
If you go north outside the west gate in Constantinople, you will see four paths. Take the one that leads southwest, and you will come across a stable. There is nothing special about it, but it hasn't been cleaned for a long time. Not only does the stable reek, it seems to emit harmful energy. Not being able to bear this, a few people have tried to clean the stable, but every time the interference of the Barbaroi tribe prevented them finishing their jobs.
If we leave the stable as it is, not only will it harm the travelers, its rotten energy will damage the land and the trees and grass will eventually die.
With your powers, you will surely be able to destroy the Barbaroi tribes wandering around the stable. Will you do me a favor, for the harmless people and damaged land?
The building that the Stable Sentries of the Barbaroi tribe is guarding, located at southwest of Constantinople, is the stable that must be purified.
The evil energy from the stable can be purified using holy water. Holy water can be obtained from Clergy Gabriel in the Constantinople cathedral, so go find him first.
When you purify the stable with holy water, filth will appear, and if you leave this then the stable will continue to exhale polluted energy, so the filth must be purified through the use of magic.
After receiving the holy water, kill 25 Stable Sentries of Barbaroi tribe, and bring me 5 Stable Filths.
