One night, on an isolated moor, Yoko, Vic and Pol are eagerly waiting for their friend Khany. When she arrives, she whisks them away on a shuttle and takes them not to one of the Vineans'' underground facilities, but to a station near Saturn. And that''s only the first leg of their journey! They''re soon invited to travel much, much further: the Vineans have decided to return to their planet, to see if it survived the cataclysm that drove them into exile.
