The Kindred native to Arachna are (unsurprisingly) spiders. It is implied that they were the first Black Widows, and their ability to create the tangled webs used by Black Widows for visions is unparalleled.
The Weaver of DreamsEdit
The inhabitants of the island utilize their powers to spin not only Tangled Webs as the Black Widows do, but to spin dreams into reality. It took them thousands of years to collect the dreams and wishes and hopes of the world and spin it into what would one day be the most powerful Witch - Dreams Made Flesh.
Despite their hugely important task the spiders themselves are very small however they are often described as being brightly golden.
