General Heddwyn's mages have engaged them, but they're not nearly enough.
— A Daein soldier, on Heddwyn
Heddwyn (Japanese: コユージョKoyujo) is a general of the Daein army and leader of a mage brigade stationed at Gritnea Tower to protect Izuka and his Feral One experiments. Late in the Mad King's War, he led the defense of Gritnea Tower against an attack by Ike and the Crimean army which aimed to retrieve the captive heron princess Leanne, commanding both beorc soldiers and Feral Ones released by Izuka.
Heddwyn is somewhat cowardly and was easily intimidated by the approach of Ike's army, panicking about how his forces weren't large enough to cope with them. He had difficulty telling the difference between the Feral Ones on his side and Ike's laguz allies, aside from Nasir, whose color did not match any of his feral dragons.
This is not good... They're closing in. There are not enough Feral Ones. Someone! Anyone? Haaaalp! Go find Master Izuka at once!
