I should have given titles for the previous posts too. Oh, well.

The Kyr religion was originally the religion of the Kyrs, a non-human race which arrived to Ynev at the beginning of the Fifth Era. It was present a very long time on the continent, went through many changes, not just by itself but it changed with the Kyrs (their life, society, politics etc.) and with the impact of the Human population brought when it was introduced to them. Now the people of Ynev - and therefore the players themselves - don't know how it is looked like in the beginning. Supposedly their religion was always about the conflict of dualities and the new stuff growing out of this conflict.
The authors listed five gods, three males: Sogron, Tharr, Weila; and two females: Igere, Morgena; but lots of smaller deities/spirits exists, they call them hekkas, they are the products of the chaotic Sixth Era, the struggle of Dawa and Ryek. When I met MAGUS, first I read ETK where Igere was nowhere but later they added her and I got the feeling there were other gods too. This was confirmed by the Handbook of Clerics and Paladins, before they arrived to Ynev they had many more. Every god had Anyrs who can be considered as multiclass cleric-mages in DnD terms, they were in the top positions of both the church and the state of Kyria, but in the wars against Orwella they all died or fled.
Igere is the creator and while her cult disappeared from Ynev she stayed the main goddess of the Kyrs left behind on Calowyn. Her sacral places were the most ornament of all the Kyr religious buildings on Ynev. She has power over the created beings and weather, she's the god of light, birth, development and old age. Her worshipers are/were first among educators and healers. She was deposed by Tharr and her Ynevian followers slowly become extinct.
Weila, the Forger of Fate (forger as in smith), the strongest of the ancient fate-gods, he might assimilated all the others. A warlike god and the central figure in the Kyr pantheon on Ynev for a long time. He's the antithesis of Igere as he's a destructive too. He has/had power over the material, nature and time, he is/was a patron of wizards. He was weakened by Tharr as well, his followers slowly disappeared.
Morgena is the Lady of Shadows, goddess of gloom, dreams and inspiration. She's an antithesis of Igere as the darker side of a female duality (Igere is daylight, she's the night). She supported Tharr in the feud so she could preserve herself and her followers, still they can worship her only in secret. Her initiates support bards and arts, they know the meanings of dreams and proficient in astrology, psychology. Witch sects seek her patronage. Most hekkas serve Tharr but one, Ilho-mantari, the patron of some thief and assassin guilds serves her.
