"It is now the beginning of the Age of Rebirth. The Compact of Dagda has broken into two factions: one dedicated to Dagda and another dedicated to one of his lieutenants, an angel known as Cassiel who argues that angels should follow the example of the One and turn the backs on Creation and allow it to succeed or falter on its own, not as part of their schemes. "

I know that one faction is the Grigori but what is the other faction? Also...

"In the shadows it is whispered that the Godslayer may not be capable of killing a god forever and Mulcarn may return; sages fear that, like Sucellus, he may return more powerful than he left. Other rumors speak that a group of men have found the gems at the center of the Elemental planes that Agares stole so long ago. They say the Gems of Death, Water and Air all are being held by mortal men, now with as much power as the gods themselves."

Will these Gems of Death, Water and Air, etc.. be implemented into gameplay? Perhaps giving unique Channeling IV spells to a select few? And what of the Godslayer today?

Not an in game faction, but rather the remaining angels that serve Dagda outside of the mortal world.

Gems, Godslayer etc would be the stuff of quests when they come in Shadow.

yeah im thinking that when a summoner trys to sommon something there coudl be a small chance of accedentally summoning hte gem or something but its probobly coming in shadow
