The Mozj'la are a daring species native to the Krolena Galaxy (Ashta Prime, in particular). They are one of the four major species in the galaxy, with the others being the Ketla, Anea and the Quarae. Known as the pioneers of modern Krolena by other species, the Mozj'la were the first to propose the idea of the Quara'ke Trifecta after discovering the nearby Ketla-Anea Alliance and the Quarae Consortium.
The earliest Mozj'la (in their current form) can be traced back as far as 342,000 BCE. It is thought they first evolved from some of the aquatic fauna of Ashta Prime, and were amphibious. The Mozj'la still retain characteristics and traits from their long-lost aquatic ancestors, such as the small gills on the top of their head and the ability to utilise these gills to breathe underwater for a short period of time. Around 256,000 BCE, the climate of Ashta Prime entered a chaotic phase in its history known as "The Destabilisation", causing a severe shift in the planet's geography. Rivers dried up while new ones formed as the tectonic plates ripped themselves free of one another, deserts began to encroach upon the great rainforests of the world while the oceans boiled or froze.
With the end of the Destabilisation in 240,000 BCE, the few remaining land-based predators on A.P. began reclaiming their lost lands, such as the Great Hunting Ground (a large continent ideal for predators due to its abundance of easy prey). It is thought the early Mozj'la were one of the prey species located in the Hunting Ground, with experts suggesting they fled the rapidly shifting climate and began grazing on the soaring green plains of Ashta Prime just as the Destabilisation reached its worst point in 254,000 BCE. Due to the lack of predators to control the population, Mozj'la numbers soared into the hundreds of thousands, with them seemingly taking the biggest boost from this lack of prey. Post-Destabilisation, the Mozj'la had to fend off against the invading predators using tactics and strategy rather than brute force. After a few thousand years, the Mozj'la tribes entered their equivalent of the Bronze Age, allowing for the construction of more advanced technologies, such as weaponry.
Around 215,000 BCE, the Xojourn tribe began constructing large temples devoted to their gods and goddesses as well as their rulers. One famous example is the temple of the Goddess of Agriculture, Hartulo, on the west coast of Khora (a small island in the middle of Ashta's biggest ocean), which is still mostly intact. This along with other findings show that Xojourn temples shared a common design, with a large, upright cylinder acting as the main building and a curved staircase up to the different levels.
