Also i was reading the fluff section of the new rulebook and i saw a drawing of a "Slanni" what looked like an athletic Slann Mage.
Whats up with that?
Alright, bear with me...
"Once upon a time, in the grim dark days of the 1980s, there was a game called Warhammer Fantasy Battle. This game was based upon the premise that armies of various common fantasy races, all inhabiting a fictitious game universe known as 'the Old World', would line up and do battle against one another. One of these races was the Slann, the weakened descendants of the Old Ones, a catch-all predecessor race with great power in the game universe.
The Slann were a race of toad-like beings with clear Aztec/Incan references. As armies go, however, they were poorly supported with models and fluff, and indeed, their fluff mutated over time. Thus, in the course of the '80s and '90s, they went from an army of fighting frogs with drugged human slaves to fat, sometimes mummified, ultra-mages served by hordes of lizardmen. And they were no longer actual descendants of the Old Ones, more like a servitor race (IIRC).
Moving back to the 1980s, game designer Rick Priestley had an inspirational moment and came up with a radical new idea: "Hey guys," he said to his mates at GW, "Why not take all these cool fantasy armies and put them in a sci-fi setting? We could give them guns and call the game something cool, like...like 'Warhammer 40,000 - Rogue Trader'. Wouldn't that be totally nifty?"
So it was that in 1987, Warhammer 40,000 - Rogue Trader, a skirmish game using the same races as in WFB saw the light of day. Of course, some of these races had changed slightly to make the game less like its predecessor, having gained different background stories and cultural outlooks. Thus, Orcs were no longer Orcs, but Orks; Dwarves were human mutants called Squats; Elves became the Eldar and instead of being noble good guys, were psychotic mercenaries and pirates, notorious for turning on their employers at the drop of a hat.
Naturally, the Slann were also transferred into this setting, complete with their Aztec-style society. They fought in random warbands as a means of broadening their minds (apparently just travel isn't enough in 40k!
), and were clearly identical to the Old Ones of the Old World. Hence, athletic fighting frogs with guns, instead of spears, but still with feathered headdresses.
Time marches ever onward, however, and the Slann were once again poorly supported by fluff and models, only this time in 40k. The common origins of the race-armies in WFB and WH40k were lost in the murky recesses of GWs staff writers' minds, and so the Slann in WFB evolved into the fat froggies we know and love today, while the Slann in 40k were essentially forgotten, with only the occasional mention of the Old Ones to remind those in the know of the faded glories of the 40k Slann."
And that's what you're seeing in the new rulebook - a 40k Slann as they looked in 1987. Here endeth the lesson.
