The base Chrono passed by had long since noticed the mages following not too far behind him, and sent word as well as a few of thier monsters to the next camp, which was about a three day travel if you were traveling by foot. The messenger and his 'caravan' kept their distance while quickly moving past the group and reaching the next camp in about a day, so the day before Chrono would come across the camp, they were preparing for the ambush.
Of course, the only thing Chrono noticed going on was some really big objects moving in sight, and then moving out of it just as quickly. I've been alone for too long, I must've seen a shadow or something...
