In the lizardmen book it mentions Nakai the wanderer, lord mazdamundi and Tehenhuien. Tehenhuien has rules in the Lustria book but are there any rules for the other 2?
Hi! For Nakai: http://uk.games-workshop.com/convershunklinic/wh-nakai/assets/nakai.pdf Mazdamundi: rules in white dwarf 290 (experimental rules) Tehenhauin: I think you can find it in the Lustria campaign book or: http://ca.games-workshop.com/CommunityNew/HOH/Army Downloads/redhost.pdf Hope this helps!
Keep in mind, however, that none of these characters are considered 'legal,' and so require your opponents permission.
A Kroxigor hero? *Drools* But could anyone please find a link to Mazdamundi? I'm curious to see what White Dwarf came up with.
