Sherd of the Aqua Blade

When we talk about power, we can't avoid mentioning the innumerable changes of its nature. The impetus of flood that eradicates trees, the vibrancy of life inside the oceans, the flowing of blood inside the veins... Water is the source of all life, and strength. In the Cult's ancient assassination training, it speaks of how "one must flow like water, to control power in all its forms". These sherds come from a sword with that teaching engraved upon it like a curse, and for those who would wield power can open a path like a water cutting through stone.
