Eru watched as Children of Forest and Giants were united and thriving together.They even made statue of him to pray to, he did warn them"You will face many dangers and your future will depend on your choices."
The children of the forest and giants bowed, while Eru was about fly away.A young leaf questioned"My Lord is there way to call you?"
Eru was ready to fly off, but turned back as he hovered in the air brazenly defying gravity.whicb only caused the children of the forest and Giants to believe in him more. He smiled at her and answered"Just pray."
As westros was progress he noticed there was also other spiritual being slowly gaining sentience one of them was a spirits like Drowned god and another called R'hllor, alternatively known as the Lord of Light, these were small time spirit that became a small deities.
Eru remembered the Lord of Light has been described as a "fire god" and its clergy "fire priests", as His worship centers around fire and light.
He remember most of the worship practices of the Lord of Light involve fire. This can range from simple bonfires, to some extreme cases advocating the sacrifice of nonbelievers by immolation. The symbol of the Lord of Light is a fiery heart. The religion is led by the "Red Priests", though both men and women can join the priesthood.
Lord of the light would have gained massive follower in the continent of Essos.But now Eru was going to cut them of before R'hllor can gain the powers of a God.
Eru was not afraid of these bengs since his power was way above them and these spirits even if they can gain so called godhood will never be able to escape the confines of the laws he placed on the GOT world.
Also R'hllor for now was a high level spirit, who was using his power to lure power hungry humans to gain power through sacrifice.
Eru grinned and muttered"Let's counter them."
Eru used water to fashion a spirit, which was named Ulmo,tall, handsome, powerful, yet gentle", he has black hair, a neatly trimmed black beard, a deep tan, and sea-greenthe glowing tattoos on his body become very faint and slowly glimmer.
This tattoos are the one in the future that will link them to the Old gods, he was more powerful than
R'hllor, who is now a high level spirit now.
Ulmo quickly knelt in front of Eru and said with utter devotion"What can I do for you father?"
Eru gesturing towards the Essos and said"As you can see son, this land I created is getting corrupted by spirits who are greedy for power.To attain godhood they are using these mortals greed and lust."
Ulmo was angry and yelled"I shall destroy them."
For Ulmo these so called lowly spirits were desecrating his father work, but Eru calmed him down and said"I know it angers you my son, but they have part to play in the future.
Ulmo was curious about what his father wanted to do, after all with fathers powers it was easy to kill them off.Eru explained"I want you to act as counter to this religion that this R'hllor is building."
Ulmo understood his father plan and said"You want to curb his influence and power."
Eru smiled and replied"You can bless your followers with powers to course these so called red priests."
Ulmo nodded as he suddenly dispersed changing his body completely into water.
Eru watched as Ulmo made his first group of followers, which was multiple villages that had been threatened and lost there families members to these Red priests.
When you help someone at the lowest point of your life they will always remember you.In gods case this can be used to get people to follow you, he used it multiple times.He knew it was manipulative, but end of the day he did not force them to follow him not did ever treat his followers badly.
Even though he was now a god, he had bias and sometimes hypocritical attitude because of his past life.
[A/N:The mc is biased towards certain families like Tyrells,Martells,Starks and even some of the Targaryens.But he won't save every Targaryen, like he will save Elia and her children, but he will take there death to make sure timeline stays the same and even mess with people so called "plans" for entertainment purposes.]
