Kingdom of Vestiria destroyed.
Military action
A human warlord named Vahsyn the Hammerer leads his host to invasion on Vestiria.
Last of elven kingdoms to collapse under human waves was Kingdom of Vestiria which, despite being supported by Kingdom of Alvaena, was militarily weak and ripe for taking.
This is exploited by human warlord named Vahsyn the Hammerer that led a host of warriors through Vestirian Sea, launching surprising invasion.
With locals soon overrun, humans settled on big part of central island.
