Extinction of the Slann
Much of my research into the great battle between the Necrontyr and Slann has suggested the deaths of the Slann after the cataclysmic plague. But I am now no longer certain this is true.
Reports are coming in from several Explorator Teams studying Necrontyr pyramids that they have seen
'frog-like men' around the pyramids. Just glimpses, mostly, but there have been two separate occasions where Priests have seen them for a protracted
period of time, and Magos Junta has reported speaking to one of them. He reported that they were interested in the evolution of Humans, Krork, and Eldar (although he thinks the frog-man used the term 'Eldar'). These sightings appears to be concentrated around the northern galactic pole.
Dozens more sightings are coming from the Tau Empire in the Ultima Segmentum. Tau Ethereals questioned about them decline to comment on the "Old Ones".
I am led to believe that reports of the Slann's extinction were purposely engineered by the Slann themselves, hiding the fact that, although low in number, they are still in existence. In fact, I am now certain that they may have had something to do with the rapid evolution of the Tau, though I have no proof of this.
Slann indeed do still exist, it might be worthy of our time to attempt to contact them and gain their aid in battling the Necrontyr. It is, at the very least, worth looking into further.
