Hu'Nrabl
The Lizardmen, by and large, have little reason to leave Lustria. Little, but not none. A Skink Priest of Azyr, before the End Times Hu'Nrabl was dispatched to the east to find and slay a mighty Goblin Shaman Crax the Clever who had managed to abscond with an artifact of the Old Ones, and reclaim the sacred ring. Leading an army and arrayed in might, the band of Shamans would journey across the Great Ocean until they arrived in the Warm-Blooded land of Bretonnia, arriving on the coast of that land which they called Aquitaine. A battle seemed likely as the hosts of the Duke arrived and mistook the servants of the Old Ones for the Beastmen, but this was belayed by the arrival of the Prophetess Anais.
Bearing the Authority of the Lady, that which the Lizardmen and the Colleges of Magic would call the Winds of Ghyran, Ghur, and Azyr, she examined the Skink for taint even as the Skink in turn looked upon her with his gaze and found there was no darkness in her soul, nor impediment to the Great Plan woven into her future. Neither found and with no other cause for bloodshed at the time, Hu'Nrabl and Anais quickly made alliance for they shared a common foe. The Lizardmen accepted it quickly, for the Skink bore the authority of the Slaan. The Bretonnians accepted it well enough, for the Prophetess had the touch of the Lady about her.
For a year the two would strive to hunt down the Goblin.
Battle after battle, putting down the perverted Orcs Crax had bound to its will with the Sacred Ring, the two hosts would hound the Greenskins further afield even as they put down several of the seemingly perennial feuds that burned within that Dukedom, and in a particular spate of irony it would be one of the more unified lands of Bretonnia when the End Times did, finally, come. The Work of the Old Ones, clearly. But the Goblin proved deeply elusive, and the ability of the Hosts to find it was buoyed only by the tracking on the Sacred Ring. The time shared caused an odd melding between those two forces.
The humans, of course, showed it the more. Symbols of the Old Ones, holy and purifying, were daubed on their clothes, their weapons, their armor. They used poison on their weapons, as the Lizardmen would, the lower soldiers at least--the Knights, of course, disdained such dishonorable things for themselves. They adapted techniques they saw the Lizardmen use in the fighting, for they were skillful indeed those warriors.
But it was not solely humans who so adapted. The Lizardmen did so as well, if to a much lesser extent. The most obvious sign was in their gear, for as it was replaced when it was broken it was, by and large, replaced with its Bretonnian equivalents. They also however, gained something of a penchant for brandy, not as an intoxicant but for the taste, and the Saurus cavalry adapted a certain amount of the Bretonnian tendency for tournies and bright heraldry. Purely as a practical matter for training, you understand.
Eventually, of course, they found the Goblin and killed him and reclaimed the Sacred Ring for the Lizardmen. And so Hu'Nrabl and the Lizardmen prepared to return to Lustria. Before they parted however, the Bretonnians gave a gift to their allies for their help: Hu'Nrabl was granted the Amulet of Fredemund, a thing of mystical potency; and in return the Bretonnian too were granted gifts.

The Amulet of Fredemund: A golden eagle touched by the Authority of the Lady. Aside from offering protection from all manner of ranged attacks, it also enhances the strength of spells cast within the Lore of Heavens. More esoterically, an...echo? Recording? Message?...Of the Lady's will has been bound into it, and speaks to the bearer, offering her advice and counsel. It has been tolerated, in spite of the possible risk, for it has not impeded the Great Plan nor seems likely or liable to at any point, and it improves the strength which Hu'Nrabl may use to cast the spells of the Lore of Heavens (also the Lore of Beasts and the Lore of Life if he had those, but he does not).
Wise to the World: Hu'Nrabl has spent a relatively extended period of time in peaceful contact with Warm Bloods. While he is not an absolute expert, by far, in their behavior, predilections, actions and so on, he does have more understanding than the average Lizardman, whose interactions with Warm Blooded are much the more likely to come at the edge of a blade and shield than in peace. Further it has somewhat expanded his horizons by allowing him to consider, though not take himself, actions and strategies and tactics that would otherwise evade the Lizardmen.
I find the idea of Lizardmen having to deal with other gods fascinating, and I really like Bretonnia, so it seemed natural. He probably would have made more sense at the beginning of the quest but eh.
