Demigods

In addition to the 7 major gods, there is a wide collection of "demigods" who also exist, many of them went missing or were killed during the devastation, and many more of them seem to be "created" through the worship of Ynbris, who alone has the power to grant such a status, how she does this and why none of the other gods do it is unknown however. Much of the information about the Demigods is lost alongside their disaperances and deaths during the Devastation, here is what little information could be collected, they are also presented in order of knowledge about them, the devils and angels having the most knowledge and seemingly being the most active whereas the giants are largely lost to history:

Raven Queen: Raven Queen, a beautiful and enigmatic figure, rarely seen by anyone except her closest handmaidens. She is brooding and manipulative, always seeking to control the living like puppets so that she can lead them or others to their graves. She relishes her control over this pivitol aspect of mortality and has been known to dare to battle with actual Gods over the souls of those she takes particular interest in. Her goals and much more about her remain a mystery as she acts through her handmaidens and various types of undead servants instead, often sending them into Tetra on various secretive missions as she wages a war not only against the living, but against the Fey and the Princes as well, seeking to capture them for some unknown purpose. Her power vastly outranks almost any other demigod. It seems she has some kind of binding pact with Martius to gain a prize of some sort after aiding Martius in conquering existence, this is likely why the cultists have such a propencity towards necromancy and have so many necromancers and stuff dealing with undead. Its unclear if she is still approving of this deal or not, but she's stuck in it.

Sends her handmaidens to deal with the party often, Selena was sent to rescue Kaden but failed.

Princes of the Fey: Prince of Falling Leaves and the Prince of Green Twigs, apparently brothers though neither have been seen in the same room together. They take turns, with the Prince of the Fallings leaves ruling for a time before suddenly the younger Prince of Green Twigs comes out to rule for the same time, the brothers dont have anything resembling a set schedule and have been known to change rule several times in a day in some cases. The Prince of Falling Leaves is colder and crueler than his younger brother, taking delight in mayham, chaos and violence such as hunts and retributory attacks against those that harm nature, animals, or fey. While the Prince of Green Twigs is calmer, kinder and seems to just want to enjoy all the benefits his kingdom has to offer, sharing it with others if they share his nature and attitude. Their power vastly outranks almost any other demigod.

Once the party had angered the fey by aligning with the shadowfell, deceiving water spirits, torturing a unicorn, but now they've earned their favor by hunting Tsara'Noga among other reasons.

The party gave her control over Ecu after she stole a vital piece, shes attempted to deal with them more but they've declined despite her "benevolence"

Brought Ecu back online with the party's aid and now continues the fight against the outsiders in space.

Null: a something of negation

Metaton: a something of power

Ecumenoplis: Revealed by Galilei Galilo to be a demigod of a "walking city" that was capable of defeating an outsider alongside Zyraxus during the second outsider war.
