Shark Bites

(The story happens right after Vah Ruta is brought back from Gannons control)

Cronus, a lone Megladon Shark, decides its time to head home after a long, unwilling journey. Years ago, when he was a pup, his mother had run from the Zora Domain while in labor. She ran due to the doctor at the domain wanting to kill her child just so she could live. Refusing, she runs.

Giving birth to Cronus by a stable, she sadly passes away from the child being too big for her body to handle. Cronus, being a new pup, was left lying alone, bound to die if not for a swordsman who found him and cared for him.

Now, being older, he returns to his home place, excited to see certain face. Will that certain person remember him?
(And yes the swordsman was Link and also, Link did bring him to the Domain countless times to give to a zora for them to raise Cronus but none of the adults liked him due to his rather large size and fish type.)
