Lore24 - The Voidstar

The ancestors of the elves, the Eldar, are called the Children of the Stars. According to their legends, they travelled to the primordial chaos that would become Aedes at the dawn of time, fleeing their ancestral enemy. In the tongue of the Eldar, the enemy is called "Tharizdun", in the common tongue, it is known as "the Voidstar".

The legends surrounding the Voidstar tell us it is a sentient hole of darkness, ripped in the fabric of the universe. The Eldar hold it responsible for the destruction of their homeworld, causing them to seek refuge and shape Aedes. 

In the last few decades, elven wizards have come forth, claiming their divination magics tell them the Voidstar is drawing near to Aedes, following the arcane trail laid by the Eldar of old. If this is true, and when the Voidstar will reach Aedes, these divinations haven't yet revealed.
