The following covers some stuff that hasn't been revealed yet in the story hour, but which is now known to the PCs (well, some of it they may not remember, or may not have been explicit, but the characters would know

).
This will be a continuing series. I'm covering Luccas here, and I will be covering Hsethmah (and maybe Corvidae) next.
(Hsethmah, god of spiders; Corvidae, goddess of ravens & death in battle)

Luccas (The Red)
From an earlier post...
Luccas the Red, cast down by Allas to bring about a purer light, one suited to beasts and people, rather than the reddish glow of a sun suited only to reptiles and creatures of darkness.
And also...
Goddess of the Red Night. Blood. Crawling beasts and verminous insects. Fertility, secrets... she seemed to have a hand in all sorts of pies, until Allas and Phastas bound her up and tossed her in the Pit.
Luccas is an ancient goddess from a more primal epoch, whose portfolio is blood and passion. When she was ascendant, the sun was said to be deep crimson, well suited to bats, wolves and serpents, and that her red light gave the world a dull warmth it lacks today. She is a goddess of carnal lusts, sacrificial blood-letting, messy birth and messy death. She is bestial and beautiful.
When she birthed Allas, she did so knowing that the world needed light other than her own. She dimmed her own light, and retreated into the night as a crimson moon, that Allas' beautiful brilliance could peel back layers of darkness in the world. The goddess of mortal inspiration was to herald the new age Luccas and the other gods intended.
Allas, of course, rebelled against her unfashionably primal parents, organized the new gods, and kicked all the old gods into the infernal realms. Luccas, though weakened, retained much of her power through the agency of Dianas, one of the only Old Gods who survived into the new age (mostly by being pliable). She kept this power largely hidden (Allas certainly didn't know), and She and Dianas were carefully (secretly) allied down through the centuries.
(Note: did you never wonder why wine so often resembles blood? Or wonder how Dianas gave a fertility spell to Athanna the Drunk's parents?)
Enough ancient history.
Luccas is the goddess of blood. Although she seems to have her fingers in a lot of pies, this is primarily because of the extensiveness of a portfolio dealing with the liquid of life. Although she fulfilled the role of sun goddess (and later moon goddess) for a while, she is not well suited to it, and knows this. Her light is dull and dim, and pulses almost imperceptibly. Like a womb, it is comforting in a weird sort of way, but it does not foster the advancement of civilization nor any other thing beyond the dull NOW.
Certain animals, well suited to her red light, have come under her portfolio by proxy, and she holds some dominion over wolves, rodents, serpents and bats. She is also a goddess of venoms, an agent of the blood, and thus has some dominion over venomous animals of all sorts.
She also has associations to both night and day, and the secrets kept by both.
She is also the patron goddess of drunkeness, healing, birthing (and the womb itself), lust (and other passions carried by the blood), vampires, blood oozes, and similar such things.
