A woodsman living in King's Landing, Hobb the Hewer was one of the many followers of The Shepherd.
Rebelling against Targaryen rule, he marched on the Dragonpit, where in the heat of the battle, he killed the young dragon
Shrykos.
Jumping on her back, he used his axe to cave in her skull, striking her seven times. Some add religious allegory to this account to suggest each strike was said to be in the name of The Seven, which is possible given he was a follower of The Shepherd and listened to his sermons about the gods.
Other accounts claim he was responsible for killing Dreamfyre, though this is highly contested due to the improbable nature of someone killing two dragons in melee combat.
He was presumed dead, killed either by her fellow dragons or when the roof of the Dragonpit collapsed and was remembered as a hero by many.
