What happened to the rest of the Darkin?
With Vaarus' new lore, it turns out the Darkin don't come from runeterra, similar to how void ceatures don't come from runeterra. Maybe it's not an entirely different dimension/plane, perhaps just another planet of some sort, but we know that because of this paragraph in Varus' new lore.
> The mortal mages of Runeterra wielded wild magic, heedless of the consequences beyond their own world. Their reckless use of magic attracted the hunger of the darkin, who sent their fiercest warriors to conquer this new world. Varus traveled to Runeterra with the second wave of invaders, and with his crystalline bow, he assassinated enemy commanders and champions, helping the darkin defeat the mortal armies with ever greater ease.
Note, this in particular
> attracted the hunger of the darkin, who sent their fiercest warriors to conquer this new world.
and then it describes the warrior queen that destroys the bridge between worlds.
> loosing the last bolt that broke the bridge to the Darkin world forever.
Which means there are still more darkin out there, right? Living on their home world? Well, except for Aatrox's lore
> Aatrox is a legendary warrior, one of only five that remain of an ancient race known as the Darkin.
So what happened to the rest? What were their customs? Their society? What led to it's collapse and eventual extinction after being isolated from Runeterra?
Please rito let us know, this is interesting.
