On this day, in the 348th year of the Boreal Kingdom, the first meeting of the rebellion was held. The Astral Guild, with intentions to usurp the throne of Boreas, sought the aid of the Klarian Guard in the war efforts. The Guild provided the guard with a newly developed form of astral magic; astral smithing*. With these newfound advancements in military capabilities, The Klarian Guard allied itself with The Astral Guild in formation of the rebellion. A new purpose and new power required a new name, and the Klarian Guard shed its old title to become The Astral Knights.

Over the coming months, the rebellion would gain traction and opposition, as an increasingly challenged Boreas sought to quell the rising forces against him. The Astral Knights made up the majority of the rebellion's military force, and would be essential in the eventual defeat of Boreas and destruction of any remnants of multiversal government.
* Astral smithing involved forging runes into weapons and armor during their creation. Each rune could be activated with a command word, and would have a unique magical effect. Each rune drew power from a specific constellation, with the ensuing effects being based on the personality and characteristics of that constellation. Any given constellation could have multiple runes that draw energy from it, each with different effects, and how powerful these effects were depended on the emotional connection between the caster and the power source.
