Chapter 1
Year 1979 , a year before Harry was born , Lily and James Potter had been trying to have a child.
Unfortunately, Lily couldn't conceive a child, since James was infertile, so they tried many many methods from drinking potions to visiting healers, mediwitches and even muggle doctors to rituals.
James, who has been raised in a family of old blood which belives in pagan gods , started to pray to gods.
Most of the gods ignored him since he was a mortal, however one of the gods interest was peeked. Poseidon; The god of seas, Earthshaker,Stormbringer, Lord of horses, decided to look at the situation. In one hand he could leave them alone on the other hand he could bless them with a child. However he decided to test them if they were worthy or not, and so he changed into his mortal form . He appeared right infront of them, which shocked the couple.
Poseidon asked them what would they sacrifice to conceive a child , Lily and James glanced at each other first and replied with everything, we would sacrifice our everything and so Poseidon possessed James for a few days , and Lily was able to conceive a child. Poseidon told them that the kid would probably be demigod before he vanished.
Lily and James were over the moon when they got news but they remembered the words Poseidon uttered. So Lily started to read on Greek and Roman Mythology as well as Egyptian and even Shinto .
James ,who wanted their child to have good , long and a safe life prayed to the gods even more and always burnt some food for them , he also delved into Mythology himself to keep the child safe
They took precautions, put wards on their home at Godric's Hallow , they also informed of the pregnancy to people who they trusted, which was pretty low because of the on going war .
They made Sirius Black , a close friend of James ,godfather who swore to spoil the child rotten once they were born. He was also informed about the probability of kid being a demigod , which made him ecstatic since the kid would be powerful.
They made Alice Longbottom , a friend of Lily whose also pregnant, the godmother .
After a Lily and James went to check the kids gender , Sirius betted a boy and James betted a girl , Lily who saw their actions just shake her her head and went to check with Mediwitch. Mediwitch informed them it would be a boy , which made Sirius happier since he won the bet and James shook his head and gave him galleons.
James and Lily were going through possible when Sirius and Remus and Peter( they are also a part of people they have informed about pregnancy , just not the part with demigod) busted in and Sirius yelled " I will found the best name " and the other were judging the names James and Lily wrote nodding or shaking their heads. Sirius, who belived he found the best name( which he did ) yelled "Perseus Potter".
James looked at Lily and grinned ."I like it mon cheri, what about you ?" "Not bad ,what are the other options?" She he looked at the names they wrote and suddenly found them ridiculous. (like who thought the name Gordion Thomas Potter? )" I belive it would be a fitting name , it would also bring good luck since Perseus was one of happy ending heroes (for them I suppose).
And so the name was decided "Perseus Potter".
