back in time adventure

As you walk in the direction of the city you see a procession coming toward the group of fishers on the sand, and as you look around you notice some of the people around you are muttering amongst themselves, and you can hear snippets of what they are saying:
"They're coming to get workers for the new canals, aren't they?"
"Well they’re not finding us, we’re hiding over there until they go back to Chan Chan!"
"...some sections of the great canal are wider across than 180 men lying head to toe! It brings water all the way from the Chicama River, which is more than 3 days walk from here! Do you know how many backs broke digging that out? Now we must dig more?!?!"
"I'm going to go and help. Thanks to the canals we can grow our food and feed our ayllu!"
