Okay I got the answe to this from playing MHFU over again and the  Pokke Village Chief said    "My ancestor... I've heard it was he a cave-dwelling man with a giant sword, who fought against the Akantor and drove ut to the Volcanic Belt.    That Heroic deed is why the local Felynes still pass down the story of Akantor in their folklore."

Guess her ancestor could have been a giant Wyverian man who knows and this is where anyone first heard of a Akantor from and it also states it didn't live in the Volcanic Belt so it must have been a wandering one like everyone is afraid of.
