When Lucas arrived on the fifth day, he noticed a crowd of people gathered around his stall but he wasn't surprised by this. Lucas had already gotten used to having people follow around him ever since the previous day.
Ignoring them, he opened up his stall before leaving once again. The act of opening the stall was a somewhat mandatory action as it implied to any passerby or potential client that the owner was around, even if there was no one present at the moment. The entire point of this was to make it so vestige-smiths wouldn't lose out on an opportunity, but at the same time, they would be able to freely explore the convention.
If anyone interested in the stall wanted to have a conversation with the owner or see more vestiges, there was a contact info pasted on the side of the stall.
