The bloody shoreline/Pantheon
The gods of the realm are not petty and jealous. Clerics of the realm aren't forced by the gods to be 'exclusive' and will frequently simply serve the pantheon. There are still some clerics dedicated wholly to a specific god, though they may channel a spell from another god when relevant, or issue a prayer to another god without it being weird. Generally a clerics domains represent the gods that they're closest to, but they can also represent that cleric as a person, too.
While there are distinctly evil gods, it's not that prayers shouldn't be made to them. Vecna, for example, is distinctly and wholly evil, but is still the patron of knowledge and magic and is respected as such (despite the fact that he'd turn to world into zombies if he could).
The pantheon in this world is somewhat fluid. It's not supposed to be possible, but gods can die. Several mortals have also ascended to the power of godhood, though their new perspective and power sometimes changed them.
This pantheon isn't complete, so feel free to add to it (via FB message, probably).
____ the goddess of Life.
____ the god of Death.
The gods of life and death are two sides of the same coin. They thought to have never been seen in the same room together -- as a result, they are usually represented together, or as one being. A coin is used as a holy symbol to them.
They do not hoard souls - they protect them. They don't protest at all about resurrections and relinquish the souls freely when bequeathed. The do not, however, let them go for necromancy, as this is abhorrent to both life and death (Any undead with a soul have to be created at the time of death).
A normal part of funerals is a minor ritual. A candle will go out to verify that a soul is now in the possession of the pair. If it doesn't go out, the soul is somewhere else, either the person is still alive (possibly through bodyless resurrection), or the soul has been taken by a necromancer.
Gil, the god of money.
Gil is named for the currency used by an ancient population (Probably a variant of the word 'gold' of the era). As the god of money, he is also the god of commerce and gambling. Common things to hear in gambling houses include "Praise Gil" and "Don't fuck me, Gil"
Vecna, god of knowledge and magic
A wholly evil and power hungry being, Vecna was a mortal who invented magic as it is known in the realm. He kept its secrets to himself and delved into Necromancy. Eventually, his thirst for power led him to directly challenge the gods in a war that destroyed much of the world and shaped much of the future. His ascent to godhood had some unexpected effects - his creation of mortal magics became available for everyone. If Vecna dies, mortal magic may well die with him.
Kleguin god of oceans
The god of the oceans. Actually an ancient Kraken who ascended to godhood. Was generally kind of evil before ascent, her newfound responsibilities changed her somewhat.
Bahamut and Tiamat
Technically not actually part of the worlds pantheon, they are a natural force that impose themselves on the world - a step beyond the worlds pantheon. They are still frequently worshipped in the temples as gods of law and chaos. The two have been at war for eternity across all reaches of reality.
