Notable extra-galactic and alleged extra-galactic species included the Yuuzhan Vong and the Chazrach, the Kwa, the Nagai and Tofs (originating in Firefist), and the Silentium and Abominor droid species which may have originated in the Yuuzhan Vong's home galaxy. The sentient ship (and its pilot) Luke and Leia encountered also originated in another galaxy.
The InterGalactic Banking Clan had influence as far as the Rishi Maze and Firefist.[source?] The Starhunter's Intergalactic Menagerie made trips to and from the outer galaxies, capturing rare animals for sale.
