"One of the reasons Red later coalesced, and built such a strong counteridentity to Blue, was their sense of grievance over this decision. We should have waited, they said. We could have had something much more useful than Cradle." Arjun zoomed in on Indonesia and dragged out a skinny rectangle, straddling the equator and spanning most of Red’s latitudes. "If instead of Cradle we had made something in the shape of a long arc, spanning a greater distance north-south, it might have connected with Asia down here, where Singapore used to be. And here it could touch the northern cape of New Guinea. And New Guinea could be connected to Australia by dropping enough rocks into the shallows between them."
