With all the gods leaving this world during the great sunderings, Clerics got the short end of the stick when it comes to godly worship for powers. Because she was the last god left in this world, Anora sired demigod twins to split the theological burden. The older of the two, Melena, represents light and hope. Morgana, the younger of the two, represents darkness and destruction. Both sisters are often depicted at odds with each other.
Anora is first and foremost an Arcana and Knowledge domain goddess, and so the powers she bestows on her most loyal followers are similar to those of wizards. Both Arcana Domain and Knowledge Domain typically go hand in hand with wizardry, which she also seems to favor.
Anora sees magic as knowledge and a way to understand the world. Her followers understand that, as she will only grant powers to those who seek to understand and protect, and will relinquish it from those who abuse it.
Anora's two daughters, the Demigods Melena and Morgana, represent light and darkness respectively.
Melena is first and foremost the goddess of light and redemption. A common saying by her and her followers is "Redemption in the Light." Her followers can be a bit overzealous, much like Melena, enough so that their "cleansing light" often is too much for some to handle. However, it is their belief that not all can be redeemed, and those who face the light and falter are of those types.
Morgana is first and foremost the goddess of twilight and darkness. Strangely, she is often more reasonable than her sister, often believing everyone can be redeemed, no matter what. While most people avoid the darkness, few know that Morgana is often more chill than her sister. She is the darkness, and people think she is often best avoided.
The church of Melena is larger than the church of Morgana, and they are often at odds with each other.
Anora grants the powers of the Arcana and Knowledge domains to her followers.
Melena grants the powers of the Light and Starfire domains to her followers.
Morgana grants the powers of the Twilight and Blackfire domains to her followers.
Other domains still exist, but do not draw their power from gods any more.
The Death and Grave Domains draw on the power of death and decay to fuel them.
The Life and Nature Domains draw on the power of nature and natural life.
Tempest Domain draws on the wrathful power of the storms.
Trickery Domain draws on the power of deception and trickery.
War Domain draws on the power of battle and war.
Forge Domain draws on the power of creation and craftsmanship.
