Nakai earned his epithet due to his solitary nature, for instead of pledging himself to a single temple-city, he goes wherever the Great Plan deems it necessary – whenever the Lizardmen are in dire need; when catastrophe threatens their existence. He is revered by the Skinks, who adorn him with tokens of his many battles fought in preservation of his race and the furtherance of the Great Plan.
Description of Nakai the Wanderer

Nakai, also called Nakai the Wanderer, is a Lizardmen Kroxigor Ancient. He is a revered creature, regarded by Skink Priests as a powerful jungle-spirit made manifest. He has travelled all over the Known World and is a mighty protector of the Lizardmen, appearing anywhere out of the jungle during times of need, before disappearing once more.He famously appeared at the Defence of Itza, wreaked havoc at the Red Fields and was recently reported at the Great Reckoning.

Nakai's presence is a tangible portent that a battle of great import is about to take place. When he appears, the Skink Priests treat him with great deference, adorning him with ceremonial wargear and renewing the gold plates and sacred decorations that are hammered into his toughened skin and horns, before he enters battle. In the aftermath of such major events, they do the same, adorning his massive, battle-scarred body with ceremonial tokens. Over the millennia of victories, Nakai has become quite festooned with such golden tributes.
