Mining the original Rogue Trader book for adventure ideas I came across the xenos Slann. It immediately put me in the mind of using them. The idea of a great precursor race still clinging to the edges of the galaxy is great and the map puts their remaining domains close to the Calixis Sector.
Has anyone run anything with the Slann or made 40k stats for them? If so how did it turn out for you?
The Slann are an extremely tricky thing to incorporate into any game of 40k, the implications of their very existence in a Sector let alone a planet are far-reaching. A single Slann, even just the corpse of one, would bring down all sorts of factions to it. First and foremost would be the Ordo Xenos and the Deathwatch followed by the Adeptus Biologis, let alond the myriad of radical groups that descend upon such a treasure. Cold Traders, Beast Houses, xenos-worshipping cults, the list can go on and on.
Now I myself have never included Slann outside of legends and myths because of the difficulty of putting them into a game and not have their presence drive the entire plot, but if you made a campaign based it then it could work.
As for stats, think someone made a Xenos Species guide somewhere on here. Dunno about its accuracy but it should serve your needs.
I'm pretty sure the "modern" Slann are much regressed/devolved from the peak of their power. If you've played KotOR 1/are familiar with that time period in Star Wars, think of what the then-modern Rakata were like, compared to their civilized peak in ages past.
It was LodgeBlackman's Xenos Character Guide where he statted out the Slann, along with other races.

I've used Slann several times. For their stats I averaged a Space Marine with a Lizard-Man.
this was pre-Lodge Guide, however.
Thanks for pointing me to LodgeBlackman, that is a great resource.
As far as how to use the Slann I was thinking of having the Serpent's Cradle be an ancient Slann super-weapon that makes stars go nova. The weapon would have been developed late in the Necron war as a last resort. The surface of course would still be inhabited by regressed Slann and their ruins.
