The royal sibling middle name is an attempt to be a balance of their birth prophecy (fate and/or personalities, i kinda forgot). Lark gonna be "too hot" and so his name is avalanche, on the contrary fernandez is "too cold" hence the name amberkeeper. Ash on the otherhand is destined to be a great figure that is loved by everyone and yet gonna ruin the empire, so they named him bornhater.
