Ulmo was now looking at village in Esso, they were threatened to be burned alive unless they provide live human as sacrifice for the so called Lord of the light.This is not the only village that was threatened, so Ulmo decided use this situation to his advantage.
He started giving leaders of these villagers visions and even pulled there astral forms to make a meeting between them.
Each village leader as follows Thoror,Gina,Illaro and Trego.
All of them were having these visions that seemed to so real and it told them that future.It was horrible.Then something happened.They felt a wrenching sense of dislocation, and for a moment all of them were pulled our of there bodies, looking at their own body from across the room.
There souls were dragged away to distant place Iit looked like an enchanting city underwater.
They all were shocked seeing fishes swim by them and they did not have a problem breathing.
All of them looked at their own bodies and saw a strange glow around them, trailing wisps of light.
Thoror questioned"What is happening and who did this to us?"
Thoror knew some of there people, since they have traded food and stuff with each other and all of then were as shocked as him.So he was sure they were no the once who bought them here.
Then everyone heard a voice it was strong, yet had a gentle feeling"I called you of you here."
Everyone turned to see 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.
All of the village leader could tell this figure was by no means an ordinary man, while Ulmo continued"My name is Ulmo God of the Sea, Storms and Earthquakes."
All of them were shocked and then quickly remembered the so called red priests and priestess talk about R'hllor the Lord of Light.
They quickly reacted and knelt before Ulmo, who told them to rise.All of the in slight fear stood up as Ulmo spoke up"Don't fear, I won't harm ypu, instead I want to help you with your present situation."
All of them were surprised at the same time felt hope, Gina took a deep breath and asked"My lord are you the one who sent those visions?"
Ulmo gave nod and explained"This whole world is created by father and R'hllor who is just a lowly spirit is corrupting it."
Thoror was in awe and asked"What do we call the creator?"
Ulmo smiled and said"Eru Ilúvatar,The One, The All High, The Father of All."
They were in awe, while Illaro was really hoping to take revenge for his brother, who was killed by the red priests and questioned"You are going to help us?"
Ulmo sighed and answered"I can give you the tools and abilities the rest is up to you."
While they were still slightly disappointed, Ulmo saw this and explained"I have divine laws that forbid me from directly intervening.....
Only one who can disobey them is my father the creator himself."
These so called divine laws where real it was something Eru created so the situations like Greek Or Roman Pantheon is created here.He didn't want a zeus situation to happen.While any so called gods created by him in these worlds are loyal to him, but they are able to feel emotions like humans so they can fall in love with mortal, which could cause demigods popping up.
All the village leader looked at each other and agreed,Ulmo blessed them with the ability to bend water in any form.Basically water bending to was something Eru told him to do.
In the future these villager a will start a religion based on Ulmo following him, also they will gather new recruits with Ulmo giving them visions like how Lord of the Light did.But they did not have to sacrifice anything, only thing they had to do was use there powers to serve the realm.
So they were able to defeat the red priests and thus create a group that coutered the Lord of Lights practices.
Also this was the start of the Ancient gods like Ulmo,Yavanna,Surya,Vayu,Indra,Mandos and there father Eru.Slowly gaining more foothold in the entire realm.
