Military action
An invasion force of Halflings, Elves, and Dragonborn seized control of Beryl Island slaying and scatttering most of the Berylfolk.
Ancient siblings of the Berylfolk races, the Dragonborn have always reviled the other Beryl Island races. Halflings, jealous of the beastfolk connection to nature and alchemy, gathered the growing Elven Empire hungry for naval conquest and the scorn Dragonborn to invade the beast homeland. A terrible skirmish ensued with most Greys leaving the island and the Cuni captured and enslaved.
