Military action
In service of their empire, the settlers of Graskul (modern Aman-Tal) have sent hundreds of harvest tithes upriver to their empire. However, the fruits of the land are as much the nymphs' property as the goblinoids'. The goblinoid population of Aman-Tal comes into conflict with the Fey. The fey’s rules of reciprocity were not sufficiently observed, so they exacted a heavy price from the residents. The retributive action nearly depopulates the entire settlement.
