The mountain summits around Tronze echoed to the sounds of various smaller bands as people gravitated towards the specific musical forms they preferred; some formal, some improvised, some for dancing, some for experiencing under a specific drug-trance. It was a warm, cloudy night; a little farside light shone a milky halo directly overhead on the high overcast. Tronze, the largest town on both the Plate and the Orbital, had been built on the edge of the Gevant Plate's great central massif, at the point where the kilometre-high Lake Tronze flowed over the lip of the plateau and tumbled its waters towards the plain below, where they fell as a permanent downpour into the rain forest.

Tronze was the home of fewer than a hundred thousand people, but to Gurgeh it still felt too crowded, despite its spacious houses and squares, its sweeping galleries and plazas and terraces, its thousands of houseboats and its elegant, bridge-linked towers. Tronze, for all the fact that Chiark was a fairly recent Orbital, only a thousand or so years old, was already almost as big as any Orbital community ever grew; the Culture's real cities were its great ships, the General Systems Vehicles. Orbitals were its rustic hinterland, where people liked to spread themselves out with plenty of elbow room. In terms of scale, when compared to one of the larger GSVs containing billions of people, Tronze was barely a village.

Gurgeh usually attended the Tronze Sixty-fourth Day concert. And he was usually buttonholed by enthusiasts. Normally Gurgeh was civil, if occasionally abrupt. Tonight, after the fiasco on the train, and that strange, exciting, shaming pulse of emotion he'd experienced as a result of being thought to cheat, not to mention the slight nervousness he felt because he'd heard the girl off the GSV Cargo Cult was indeed here in Tronze this evening and looking forward to meeting him, he was in no mood to suffer fools gladly.

Not that the unlucky young male was necessarily a complete idiot; all he'd done was sketch out what had been, after all, not a bad idea for a game; but Gurgeh had fallen on him like an avalanche. The conversation — if you could call it that — had become a game.
