Tidnab eggs are so rare that no one, not even the SAR Center, knows much about them or where they come from.
Tidnabs are notorious thieves and swindlers, making them an unwelcome sight anywhere on the Northern Plains and Leila. They can be seen prowling the streets of Leila after dark casing buildings and looking for easy targets. Somewhere in the deserts around Leila is the main base for the Tidnab thieves guild. Authorities have searched for it for decades and every time they get close the Tidnabs slip away to a new location.
