Shangdi Eteru, The Aetherium Leviathan

A lucky dragon that is seen in visions residing in the clouds. His scales look like the scales of a red koi fish but are as strong as the strongest metal, a beard and mane as white as the clouds, eyes as blue as the sky, and antlers as like branch sequoia trees. Legend has it his scales created the metallic dragons while his mane created the imperial dragons. This all occurred during the fight between him and his siblings: The Ruby Dragon and the Demon Drake.
The Aetherium Leviathan is known as the god of improvement, empathy, and righteousness. All he wants is for both the mortals and the gods to improve themselves, mentally, physically, and spiritual. By doing so, he believes that will bring true peace to the universe itself. He also believes that by improving yourself, will allow you to help others and stop evil whenever it shows its face. However, he denounces the idea of killing as the best option. War and death are sometimes needed, but only as a last resort. Empathy is needed to know the situation and to possibly help bring your foe to light, but if there is no other way, death will be considered.
His followers continue to improve themselves on a daily basis. Continuing to challenge themselves and embracing those challenges for the sake of themselves and others. They travel the globe, try to help anyone who is suffering, bringing redemption to those who have fallen, and destroying evil if there is no other way. They do not preach their god, for they believe preaching their deities name is prideful. They will only preach if people ask about the Aetherium Leviathan, and only then will they explain his ways.
Edicts To improve yourself and others (physically and mentally) for the betterment of yourself and everyone around you. To help others find the right path (this includes the corrupted people that lost their way). To only kill if killing is the option.
Anathema To indulge in self gain through the suffering of others. To use murder as the easy solution. Create fear in people through violent acts
