User blog comment:Frodo the 9 fingered/How did they kill Aleconyus?/@comment-3146930-20111024020024

My idea is that because Arion is the son of Poseidon and Demeter, it is a type of god. Making it that Hazel and Frank could kill him. The other idea is that unlike the other Giants, he is immortal only in his homeland and once outside of his territory, he can be killed
