Astrals

Believed to be blessed by the Pantheon, The Astrals were an ancient race of magically-inclined mortals who used to dominate the planet. Eventually, they fell prey to Illdaeron, and caused The Calamity, the largest disaster Sillania has ever seen.

Origins
No one knows for sure how the Astrals came about, but it is believed that they were a creation of Alnora, the intended denizens of Sillania. Though if this is true, her motivation in creating the planet and the Astrals remains unknown.

The Astrals were united under one banner from their creation, and used this unity to expand and create a civilization the likes which was never seen before and hasn't since.

The Calamity
The Astrals were the ones responsible for The Calamity, giving in to the temptations of darkness and making a deal with Illdaeron in exchange for the power to travel between planes. They never achieved this, however, as Illdaeron betrayed them, using their Nexus Gateway to invade Sillania and destroy their civilization

Ruins
Though the Astrals are gone, their legacy lives on in the many ruins which can be found across Sillania. Many of these are just small instances such as towers or caves, but there are some abandoned cities and complexes which daring adventurers may try to navigate in search of valuable ancient technology.

- Sildaman, an Astral city located underwater off the coast of Caliburn. Believed to be the capital of Astral society.

- Sildorus, a floating island which was brought down to the ground in the calamity, now existing as part of the Island Chain of Ankoa.

- Silduar, or The Halls of Bjorna, is a complex located deep within the mountains of Ravenholdt. Many aspiring young warriors are sent to plum it's depths as a right of passage on the way to manhood.

- Sildir, an ancient city mentioned in numerous texts as the location of The Nexus Gateway, although it has never been found. Believed to be in the Southern hemisphere.
