The planet Tepasi has been a longstanding member of the galactic community and was among the founding members of the Galactic Republic more than twenty-five thousand years ago. It is a world of idyllic rolling plains and verdant forests - the domain of the predatory achtnaks - as well as relatively extensive polar caps encroaching far into their respective hemispheres. However, despite its undeniable beauty, the planet is not without danger, as its surface is prone to earthquakes.

Tepasi was originally settled by colonists from Kuat roughly twenty-seven thousand years ago, who had arrived in the legendary sleeper ships that had enabled the human diaspora from the Core. In the eons that followed, the world became a center of commerce and trade and swiftly rose to prominence within the nascent Galactic Republic, as sentient species from all over the Core and beyond arrived on the planet. Human families with a direct lineage to the original colonists rose to become noble merchant houses with a firm grip on Tepasi, particularly its wealth.

Most of the millennia-old metropolises were built in the northern hemisphere and house the majority of the world's population, while a sizeable portion of the planetary industry and manufacturing were established in the southeastern polar region. The rest of the southern hemisphere is largely made up of untouched woodlands, with only a few smaller cities dotting the lush, green forests. Several Tepasi noble families have established mansions and estates in this area, with the largest and most notable residence belonging to the powerful and well-known House of Tagge.

During the Clone Wars, Tepasi sided with the Galactic Republic and was the target of several Separatist assaults as a result. After the Second Battle of Tepasi, the planet briefly came under a CIS occupation, but was liberated several weeks later by a Jedi and Republic task force, in conjunction with a planetary resistance movement funded by the Tepasi nobles. In recent times, the ruling houses have sided with the Tenloss Syndicate and allowed them to use their world as a base of operations.
