The hideous and hairy Houtsunomuh is the mythological Stalker of Graveyards and Eater of the Dead, one of the Eight Great Monsters of Enohountsun mythology.
Those who have created the world. Those who are few but seem like many. Those who will be worshipped forever, if but in a different guise.
The Old One is the living core of Tarrod.
Midian is a dark fantasy game. Most churches in Midian are moral belief structures & guidelines rather than a system that contains a deific figurehead (or many such) and an afterlife.
Context: The gods of Zetacron are physically present in the world. You can go and meet them if you like. Additionally, they are very human, with flaws and quirks—possibly more than regular people.
When the Gods forged Creation they imbued everything with a spirit of its own, a soul so to speak. The trees, the bushes, serpents and birds, everything was imbued with a soul. Even the very earth and the mountains got spirits of their own, as did the winds, the rain and the storms.
Angels are the guardians of Order, the forces that oversee that the purpose of existence is indeed fulfilled.
Demons are the darker emotions, the destructive forces of creation. In primeval times the demons awoke alongside the gods and the angels, and were herded by the greater powers, chased into hell, even as the angels were led into heaven.
A PC Conjurer or summoner, basically any mage whose sole purpose in life is summoning creatures to aid in battles and various situations, is cursed with a hex, and needs to find a way to undo the curse...before he goes mad, or his fellow PCs throw him out of the party, or worse.
Everything he/she summons, never goes away. So you'll have to figure out what the heck to do with that dire bear or fire elemental once it's done fighting the orcs for you. Eventually a caravan of bizarre creatures either annoyingly ends up following the summoner around, or they go off to cause mayhem elsewhere. Bad news for the poor spell-caster regardless.
