Sa'Vasku (SV) alien bioships

The Sa'vasku have been around for a long time, and have seen many younger starfaringcivilisations rise, falter and die over the millennia. The Sa'Vasku themselves are huge,almost immobile creatures that live a semi-aquatic xistence surrounded and tended bytheir myriad biotech constructs; they are not immortal, but are incredibly long-lived byhuman standards, with lifespans into thousands of years. There are only a small numberof actual Sa'Vasku on each of the worlds that form their domain, and they seldom leavethose worlds, carrying out almost all contact between their own worlds and with otherraces by proxy through their constructs.
