This is the first major story, with the main characters joining the Reclaimers and finding powerful artifacts.

Fantasy

A group of wizards and sorcerers known as the Ancient Stargazers built the city of Starminster to pursue their study of the Arcane secrets of the stars. They began to seek magical artifacts for their studies, and at near the same time, The Order of the White Crow begins to enchant their items and achieve greater power. Unable to convince the Order to give up some of their artifacts for their purposes, the Stargazers learned how to do it themselves, resulting in an influx of magical items, both powerful and subtle.
...
The Order of the White Crow was gaining power, but had been found out. They intended to summon the White Crow, a colossal white dragon from the Ethereal Plane. Doing so would result in mass terror and destruction. Armies met to destroy the Order, but in vain. The great armies from across the realm were wiped out quickly. The Order's power was too great, for they had powerful magical items bolstering their strength. At long last, from out of study came the Stargazers. Equally powerful, they cannot hope to defeat the Order, but rather elected to banish them to another plane of existence. The Order was ready for this, however, and revealed a new item known simply as "The Tome", which was a large spell tome with its own conscience. It was able to learn the banishment spell the Stargazers used, and reflect it back at the caster to banish both the good and evil to separate planes. With neither the Stargazers nor the Order remaining, their Relics fell to thieves who collected, sold, and scattered them across this continent and beyond...
...
Now, some yet-unknown magic users are attempting to re-summon Champions of the White Crow. This was all foreseen, however. The Reclaimers of Starminster were formed to collect and protect the artifacts of power, to keep them safe from evil. After Wizomal and Vaconto find one item of power, they are contacted by the Reclaimers and asked to join the search.

Automatons exist, but they are powered by magic rather than electricity.

The laws of Conventional Physics still stand, except for the effects of Magic (I.e. Conjuration, Transmutation, etc.) and other planes of existence.

Magic works as detailed in the Core Books of D&D 5e.

Cassander and Havelock fought in the White Crow War.

The Order worships the White Crow as their god, and summoning it would begin the age of reckoning, where nonbelievers would be destroyed and the Order would ascend to eternal glory.
