Welcome sonic travellers, welcome to the Isolated System. You must be wearied from your journey. Please sit, rest a little. Catch your breath for there is much dancing to be had and we want you at your best. Now, as you may or may not know, we don't like routine in the Isolated System, so please deposit all worldly items in the bins provided. All you need here are your ears and feet. Heads are optional, but we advise to leave them too. These days they are all filled with work and worries anyway—contraband in this particular nebular. Besides, they are distractions from the important matters at hand.
