The Constellations - Cirlce of Stars

About

The worship surrounding different constellations is the work of a more recently founded Circle of Druids and currently centers around the worship of three main deities: The Sun, the Moon, and the Night Sky. The constellations that represent these deities take the form of the Archer, the Chalice, and the Dragon respectively as found in the class features. There are a number of other stars that form various constellations in the night sky, and are valuable additions to the collection of star maps these druids collect - but they are rarely celebrated, and do not command worship as these main three do. They are, however, often referenced or represented in the druid's own folklore and symbolism, often likening morals or teaching moments to stories connected with these numerous other constellations. 

History & Origin 

These deities grew into their new divine power due to the dedicated worship of this particular sect of druids. After many Druid leaders had passed away and been offered up to the stars according to their circle's practice, their souls, in turn, began to form new stars within these three major constellations. The passing of a leader is a major movement for the circle as it not only reinforces the assertion that these main constellations represent these 3 deities, but the new stars that form further define their imagery (the detail of the constellation itself), and also further the need the druids have to study and track the stars themselves. It all connects together as a way to worship these heavenly forces, to update or replace their older star charts, as well as connect with their ancestors and the relics they left behind. The divine power and magic are the direct result of a collection of these many noble souls over time. 
As the worship of this first circle grew stronger, and in turn the heavenly power grew, there were a number of gifted few who commanded a strong control over their astral powers. These chosen few were responsible for naming and solidifying these deities as the great powers they are - they underwent an expedition to affirm the position of the stars, travel the land, and immerse themselves in study. Their goal was to find and return not only with updated charts, but also bring back items, artifacts, and stories symbolizing the journey and their discoveries, what it all meant to them. After their return, and over many generations, the Symbolism representing these deities grew more solidified, and their tenants and ideals more clearly outlined with the help of these gifted few, and the more direct communion they could reach with the heavenly powers.
These gifted few were also given the authority to lead their own development of a new Circle, following the paths from their former pilgrimage and officially founding a new place of worship of the Stars. They would take some of the followers and develop a new branch, a new community.

Worship

This religion is cultivated by the worship of three major deities that command power over the stars themselves - the Sun Father (God), the Moon Mother (Goddess), and The Night Sky (Nebulous, Goddess).  
All three deities have similar moral guidance, and do not exist in direct opposition to each other, but rather coexist and differ more in their tenants and how they are worshiped. The Sun Father, for example, is a good-natured deity who believes more in following law and order, and the inherent goodness of those who abide by rules and structures more strictly. On the other hand, the Night Sky is often a formless, nebulous goddess, aligned with chaos or "evil", and blesses those who bring down corrupt structures or institutions of ill will. Although named for the darkness that exists between the many bright stars, she does have her own constellation in the form of the Dragon, appropriately aligned for her short temper and wicked rage common in folklore. Between both extremes exists The Moon Mother, more often depicted as a fey creature, and more neutrally aligned - she is associated with trickery and deceit in the nature of fun, and in fact often toys with the Sun Father on principle alone, all while reining in the chaotic fury of the Night Sky. 

What about the dark places between the stars? Don’t you realize that’s where the good stuff is? - Tasha 

As is common in nature, these three cannot exist without each other, and neither one nor the others are perfect beings, or absolute in their teachings. Nature is often about balance, and this polytheistic religion reflects that within its own teachings.

Religious, Druidic Circle

From Tashas, regarding the class: 

The Circle of Stars allows druids to draw on the power of starlight. These druids have tracked heavenly patterns since time immemorial, discovering secrets hidden amid the constellations. By revealing and understanding these secrets, the Circle of the Stars seeks to harness the powers of the cosmos.
Many druids of this circle keep records of the constellations and the stars’ effects on the world. Some groups document these observations at megalithic sites, which serve as enigmatic libraries of lore. These repositories might take the form of stone circles, pyramids, petroglyphs, and underground temples— any construction durable enough to protect the circle’s sacred knowledge even against a great cataclysm.
