A quick overview of the dominant pantheon as presently worshiped in the Imperial Sultanate of Shalasia:
Athoth, the Voice and the Heart: The heat of the sun and fire, metaphorically and otherwise. Athoth is the most-worshiped deity in Shalasia.
Aveyn, the Weaver Lord: The world of sorcerous power. Few people who are not wizards (and wizards are extremely rare themselves) have a very clear idea of what that even means. Mostly receives offerings from people who for whatever reason wish to (or fear they might) deal with (or become themselves, or already are) wizards or sorcery.
Damerok, the Prince Beneath the Sea: Fishing and undersea creatures. Mostly receives offerings from fishermen and their dependents among humankind.
The Dark Lady of Night: Darkness and the unknown. Not really openly worshiped in Shalasia, though her faith was very popular in ancient times. Does not appear to have a name other than "The Dark Lady." Is somehow bound up with the faith of Nahl (which is not a pantheonic religion, and therefore not listed here). Many people make offerings to the Dark Lady when they have anything important to do (or just for any reason need to be out late) at night, or need to keep something hidden or secret.
Darzien, the Lord of Death: The aging, death, and decay of living things. Not openly worshiped, but receives many offerings at his temples by those who fear he might otherwise come sooner (and probably from others who want him to come soon for someone else in particular; also note that "not openly worshiped" is not the same as "not worshiped.")
Ensylan, the Forest Maiden: Forests, jungles, and trees. Not a popular faith in Shalasia, but some shipwrights and rich Pashas' gardeners do appeal to her or even worship her outright.
Estel, the Lady of Starlight: The beauty and mystery of the stars. A quietly popular faith in Shalasia, though nowhere near on the order of Athoth's.
Forseti, the Just One: Law, justice, mercy and punishment, fairness, and honesty. Until recently, worshiped by some in Shalasia and given lip service by many. Since the outlaw of his church by the Sultan however, and the rebellion -- led in large part by churchmen of Forseti -- that was crushed by the Sultan's forces, most of Forseti's one-time Shalasian worshipers have fled to Espava or perished, and those who remained have mostly turned to other faiths. His name is now rarely even invoked in the Sultanate. In spite of this however, and in spite of his church's warnings to the contrary, crime levels, corruption, and other signs of injustice and dishonesty in the nation are pretty much unchanged since he was worshiped openly.
Frei, the Lady of All Desires: Love, passion, and all unreasoning emotions and desires. Frei has many worshipers throughout Shalasia, and vast ornate temples devoted to her name.
Isiyes, Mistress of Secrets: No realm; fallen from power. A relatively small number of Shalasians still do her homage, officially as a handservant to Athoth.
Karha, the Winter Maiden: Frost, ice, cold, snow, sleet, and winter. A very slim following in Shalasia is growing quickly among those who can afford to know what "cold" or the like even means -- and wish a piece of it for themselves.
Kerranas, the Lord of the Hunt: Beasts, hunger, blood, and hunting. A number of nomadic desert tribes still have totems to Kerranas, but his faith is otherwise not very popular in Shalasia.
Lanya, the Maiden of Moonlight: Virginity, the birth cycle, and moonlight. A relatively popular faith in Shalasia, depending on the circles in which one moves.
Lyosen, Maiden of Light and Music: Art and artistic inspiration. Her following in Shalasia is relatively small but fervent, and just about anyone who has anything creative to do is likely to make an appeal at one of her temples.
Makhaseth, the Great Ward: Guardianship and protection. An old and popular faith that doesn't necessarily have anything to do with combat, unlike...
Matorath, the Warlord: Battle, war, and conquest. Well-known and often invoked out of context.
Mernos, Mistress of the Deeps: The waves and currents of the sea. Mostly receives offerings from people whose livlihoods (or lives, if they're about to travel) will depend on her ocean's placidity (with of course the occasional prayer that she swallow up some enemy).
Shaer, Lord of the Dawn: Light and the advent of light, spring, birth, hope. Probably the second-most-popular faith in Shalasia, though lacking Athoth's official stamp of Imperial approval.
Sylthos, Mistress of the Winds: Weather, sailing, and breath. Typically receives the same sorts of offerings given Mernos, but also retains a small following all her own.
Thesmos, the Harvest Mother: Fertility, agriculture, child-rearing, and the home. Extremely popular along the rivers, between the cities; less so in the cities themselves and in the wide expanse of the desert.
Vammakhel, Maiden Pain: Cruelty, pain, and suffering. Not openly worshiped (note "openly" though) -- and no openly-known temples at which to make offerings. Most people who invoke her name do so in the course of wishing her attention on an enemy or (more often) a stranger who annoyed them on the streets.
Varekh, the Lord of Earth and Stone: Gravity, earthquakes, volcanic action, and the strength and solidity of stone. A modest following in Shalasia, concentrated in the northern mountains and among the desert nomads to the south.
Woen, Lord of Wisdom: Knowledge, wisdom, planning, and memory. A pretty basic, pretty popular faith in Shalasia.
