Why should we not? There are factors, which we all agree to call “cosmic,” over which we have no control, and which may not be foreseen. All evolutionary engineering is subject to these chances. If we did not permit ourselves to begin any development on a newly discovered planet, or one that has become suitable for development and use, because of the threat of cosmic alteration or disaster, then nothing at all would ever be achieved.

Canopus, like ourselves, has experienced disappointment—and worse—in their career as colonisers. Rohanda was not the only failure. I am calling it a failure, though I know they do not—but it is no secret that I have been generally known throughout my career as belonging to that body of opinion that finds Canopus sentimental. Sometimes to the point of folly. What else can we call attitudes that are often uneconomic, counter-productive, wasteful of administrative effort?

What else? Well, I have learned that there are different ways of looking at things; though I do not yet share these viewpoints. That is, I hope, for the future… meanwhile, I am saying that judged from the immediate and practical view, Rohanda was not only a failure but perhaps their worst; and yet this was not at all or in any way their fault. And why should some of us be so ready to ascribe blame to Canopus, when we were, equally with her, ready to use Rohanda for as long as was possible—for millions of R-years, as we then thought was likely to be the case?

The disposition of the land and seas was roughly, very roughly, the same as it is now. There is a central mass of land fringed with promontories, peninsulas, islands. Around it is a vast ocean, with islands, some of them large. There are two continents, separated from the main landmass, and joined by an isthmus which has sometimes been submerged, and these are now referred to as the Isolated Northern Continent and the Isolated Southern Continent.
