Lycians
A people with a wide array of characteristics and types, most resembling various mammals one would find around the world. From Lupine to Vulpine to Cervine and everything else, the Lycians are defined by their differences between each other.
At one point, the Arathans attempted to colonize the Lycian continent, though that eventually ended in failure. The Arathans and Lycians came to a tenuous peace eventually before the collapse of the world.
Notable Lycian Subspecies: Jakkai
Notable due to their unique reproductive method compared to other Lycians (Eggs, much like Arathans) as well as their general inability to work with magic, the Jakkai were a relatively secluded race of Lycian until their abrupt and sudden disappearance some time before the world ended. Only one individual was left behind, though that information was kept secret to most.
Xena, when asked about Lycians and Jakkai relations
"...Yes, I know Jakkai are Lycians? Why the fuck are you asking me?"
Excerpt from Kayde's Notes
Something that has dawned on me recently is that, despite my whole life indicating to me that I am Lycian, I am absolutely not Lycian. I may have grown up in Lycian culture, but Arcanians seem to exist wholly outside of Lycians. This has become impossible to ignore, as there even exist Arcanians who didn't even originate in the old world - for example, the one Avali I met in Ahmit. What this implies for me, personally, is still hard to say...
