Asho Zoroaster

'Asho Zoroaster' is a double reference: first to the legendary prophet of that name, and later to the vehicle of Ransom's Crew.

Asho Zarathustra Spitama

This is the name, or title, of a religious leader (native planet unknown) believed to have introduced monotheism; moral afterlives; and the 'endless struggle of good against evil' (culminating in an escatological battle) to later religions. Little or nothing is known of his life. He is often depicted as a bearded man in white robes, with a turban on his head and a bull-headed golden/brazen staff in one hand. Some legends place him within memory's distance of Antiquity, and associate his 'Ahuras' (gods of virtue) with the Iname and 'Dívs' (gods of oppression) with the Eladamri.

G.S.S. Jaldichal/Asho Zoroaster

This was a courier-class space-ship given Marcus Ransom by the Gudersnipe Foundation, as his vehicle exploring the Known Worlds. Although no more sophisticated than any commonplace vessel, it was the stuff of science-fiction/space-opera on planet Altronis, where it formed the base of Ransom's rebellion against the local kleptocracy.
