A new race – the Order of Knights of Elrath.

Eagles are interesting, but the ability is like that of griffins.

Sorry, but I didn't have enough inspiration for the race. But otherwise, it's not bad, right?

Tibvar, you came up with a good idea, but you need to replace the angels, they are already in Heaven. You could also add another animal, for example, a Pegasus - a silver Pegasus - a divine Pegasus (Pegasus is a symbol of pure, heavenly, wise, and divine, and I think it fits here)

But otherwise, everything fits very well.

In my opinion, pegasuses wouldn't fit very well into the game, so I decided to replace the angels with a Holy Adept (Guardian of Heaven - magic of Light lasts twice as long on him and can increase the morale of volunteers/parishioners/pilgrims by +2) - a Celestial Squire (spells "Holy Word", "Divine Vengeance", and "Baptism" (removes Dark magic from all his warriors and gives a bonus morale point)) - a Demigod (Son of Elrath - automatically inflicts "Divine Vengeance" on attack and has a 50% chance to use a magic mirror).
So, is it better now?
