The penthouse apartment of the Isos Building on Mezlagob was a twenty-room suite on the top floor of the exclusive residential complex. It featured a number of bedrooms, a holofilm theater, a bar, a small gymnasium, a private landing platform, and (for at least its last two owners) a secure hyperwave transceiver. The penthouse had transparisteel walls, which could be opaqued for privacy or cleared to permit a panoramic view of Mezlagob's commercial and government districts. The entire floor was accessible from the inside only by turbolift, and beings riding to the top floor needed code cylinders to grant them access.
Noran Caapa, CEO of MezArms, owned the penthouse at one point. He later sold it to Tariun Sakaros, Phoenix Prince of the Golden Empire. While Tariun owned the penthouse, a second turbolift was secretly installed, linked directly to the basement of the building and an emergency evacuation speeder.
