Denaxi was an inhabited planet located in the Beta Quadrant. Before the abolishment of the Romulan Neutral Zone in 2387, this planet was near this border region.
It was a frigid world with snowy terrain, and experienced severe blizzards. It was home to the Denaxi Depot, a transportation hub overseen by the Xindi-Reptilians. (PRO: "Crossroads")
The planet's name was not stated onscreen but was given by Aaron Waltke in a tweet. [1]
