The first phase of the contest needed those of the Sect of Hedon to decide who would be the participants, and who would act as the scammers who were supposed to set up stalls.
Not everyone was raring to go against Daneel. Ambition was not always a very common thing, and that was also on display here, as quite a few placed their primary goal to be that of scamming the scammers, and walking out after earning as many resources as they could.
Still, many decided to take up the mantle of scammers, and hence, they dispersed first, to privately think and decide what they were going to do before coming right before the event started so that they could set up their stalls.
