Her homeworld is, of course, not in common as Thri-Kreen cannot verbally speak. But, translated, her homeworld’s name is referred to as The False Territory. The land there is mostly desert and arid, with many different clans making their home across the globe. Thri-Kreen clans often create vast tunnel networks, with their leader finding home in a termite like mound.
The Thri-Kreen did not achieve space flight themselves. In fact, their society is quite primitive, made of a monarchical system or a hunting band. They entered space due to races attempting to settle their land. Many were chased off or killed, but some had friendlier receptions, which ended up introducing the Thri-Kreen to the galaxy.
However, there is currently a problem happening in the False Territories. A parasitic fungus has spread to many different clans, including Ender’s. It takes over the Thri-Kreens body, and makes them into a zombie. It’s unknown if it’s left the planet.
This is the main reason Ender as moved to a different world and is in study of medicine. She left when she was very young (but still an adult), and has some experience on Spelljammers before. She and her clan left their planet together, but Ender found her true calling in a college on Apherra, and ended up staying there while the rest of her clan split. Initially turned away because of her lack of funds and schooling, she struck a deal with the college to let them study her and get education in return. She has a fascination with different races, as her species doesn’t have any written record of others.
She has found immense love for the current planet they reside on, and has many happy memories and friends.
