The Tchuukthai species's planet of origin, their homeworld, was located far within the Unknown Regions, residing within an uncharted system. Details regarding this world and its indigenous inhabitants were scarce and often untrustworthy. Despite multiple encounters with Tchuukthai by explorers, many opted to steer clear, perceiving them as hazardous creatures. The precise identity and whereabouts of their planet were kept heavily concealed.
Thon, a Jedi Master of the Tchuukthai race, originated from this very planet. However, he consistently refused to divulge any information about his background when questioned by his fellow Jedi. Forming a bond with another Jedi Master, Thon worried that revealing his origins might expose his people to potential exploitation if the sentience of his kind became common knowledge. His Master pledged to safeguard their secret. Consequently, while Thon left his planet, he remained the sole Tchuukthai documented to have journeyed into the galaxy for millennia. Some theorized that other Tchuukthai had left their system, possibly ending up as pets or displayed in zoos.
