The Mattri asteroid base functioned as an asteroid base situated within the Mattri system. It formerly provided a central hub for Garm Bel Iblis's privately funded resistance against the Imperial forces, known as Peregrine's Nest.
Sena, when questioned regarding the quantity of bases utilized, indicated that the current base was "Fourteenth..." "...That's if you count Womrik and the Mattri asteroid bases." Lando Calrissian, however, subsequently expressed skepticism concerning the validity of her claims, recognizing the enduring nature that Peregrine's Nest had assumed. The base she mentioned, or even its supposed location, might not have existed at all.
Furthermore, it remains uncertain whether her use of the term "bases" implied a solitary base at Womrik and another single base on the Mattri Asteroid, or if multiple bases were scattered throughout a Mattri Asteroid Field or Belt.
