Vampire hedgeling Dunk, he was bitten by Egg at the tavern and doesn’t understand what is happening to his body, the reason Egg bit him is because he saw a big and strong person capable of defending him and keeping him safe. He knew from the very first moment that Dunk was reliable and would defend him against his brother.
Dunk doesn't realise he's becoming a vampire, his skin blisters too long in the sun, he eyes ache whenever he's outside, he's been hungry before but now it's an all consuming pit in his stomach demanding something he cannot name, his canines had fallen out and sharp pointed teeth have replaced the old ones, these ones cutting into his gums and it feels as if his limbs have been grotesquely extending themselves, he tries to look into a mirror and see the physical difference himself but every mirror he finds must be broken for they do not show him in its surface. He feels a stranger in his own body. All he does now is sleep through the day, and roam at night, he does not know why he wonders just that he knows he's looking for something.
Egg is excited to have a fledgeling for himself, his family had forbade the younger Targaryen's from making ones just like them until they were presented to the family and given approval, but Egg didn't want them to turn his noble knight away when he had only just found him. So when Dunk laid himself to sleep, he had snuck his way to his prone form and turned his head away till his neck was in full view. When he bit down, Dunk had grunted and tried to squirm away but Egg had used his strength to hold him in place, when Egg had felt the tentative bond form between them he was ecstatic.
Egg wrote his aunt Shiera to have her come to the tourney and put protective spells on Dunk to protect him from the sun, afterwards he left to find a woodworker to make his new fledgling a coffin. Only the best for his shield.
