All good space opera has a spaceship at its heart, and this is mine, the freighter Alcione. 500 meters and 180,000 tonnes dry mass of starship, designed as a series of modules along the main axis. It might look spaceous but it’s not; the crew and passengers are crammed in the little radiation shielded, one gee module at the far left. Other modules are for biospherics and zonal translation (aetherspace, etc), hanger, machine shop, etc. The cargo is in huge containers placed between the front and rear Alcubierre rings. The Daedalus drive is the huge fusion torch at the right, located a safe distance from the living quarters and life support. The triangular wings are actually high performance heat radiators.
The Alcione is mentioned in Madverts, but makes a full appearance in the fourth or fifth novella of the Freehauler Alcione series.
