The deities can be categorised as the groups below. Note that these groups do not necessarily define a god’s allegiance. For example, Prometheus was originally a Titan, but sided with the Zeus (Olympian) against Kronos (Titan), he then later betrayed Zeus to deliver fire to humans.
Chaos was the first entity to exist, they are older than the cosmos itself. To worship Chaos is to worship absence and nothingness. Chaos does not grant any boons or rewards for worship.
Worshipers of Chaos are widely considered untrustworthy or deranged as worshipping the concept of nothing doesn’t make sense to most people.
From Chaos came the first Primordials; Gaia, Tartarus, Erebus and Nyx. Together they sired the other primordials.The Primordials built the natural world and thus are usually chaotic in nature.
Primordial worship is seen as unusual since most of the primordials have been stripped of their power.
Every night, Uranus covered the earth to mate with his mother Gaia. They sired the Hekatonkheires, the Cyclopes and the Titans. The youngest of these titans, with help from Gaia, castrated his father and flung his genitals across the sea. Kronos imprisoned the Hekatonkheires, the Cyclopes and many other Primordials before taking his father’s place as leader of the gods.
Titan worship is more accepted than Primordial worship, however it is still seen as somewhat unorthodox, especially those titans who have been dethroned and imprisoned, such as Kronos and Atlas.
Kronos feared being deposed by his child, as he had deposed his father, so he decided to eat his children as soon as they were born. He did this five times until his sister and bride, Rhea swapped baby Zeus for a rock and hid him away on Mount Ida. Eventually Zeus returned to his father disguised as a cupbearer, he poisoned Kronos, forcing him to throw up Zeus’s siblings, the first Olympians. Together the Olympians overthrew Kronos, Zeus became the king of the gods and eventually was able to form his council of twelve olympians. Alongside lesser gods the Olympians now rule the cosmos.
The Olympians are the most popular gods for direct worship. Nearly every settlement with more than a few dozen people will have a shrine or temple to at least one of the Olympians.
There are many gods and deities who were born to primordials, titans and olympians but do not identify themselves with any particular group. They tend to focus on their personal domains and followers, choosing not to follow Uranus, Kronos or Zeus directly.

For warlock patrons, speak to me, and we can decide who exactly they are. The table below are possible examples, we can discuss any powerful beings found in greek history/mythology.
Here are some notable figures in greek mythology, many of whom could be viable patrons: https://simple.wikipedia.org/wiki/List_of_figures_in_Greek_mythology
Note some of these may conflict with the Cyranos version of the Greek pantheon and may not be accepted.
