When it cuts through the wind, high in the sky, its opponents shudder in fear and despair.
Many who were skilled applied to control this terrifying weapon. but failed and were deemed incompatible. Islay volunteers for the experiment to prove her loyalty to the King, and passes miraculously.
Proving to be the castle's last line of defense against intruders, she reigns over the skies of the Kingdom.
