Mia watched as her father and Ford covered their horses' eyes with their coats, securing the makeshift blindfolds carefully to the halters.
Both barefoot, the men were risking getting stepped on by their mounts rather than have soaked boots that would impede their speed in case fleeing became necessary.
Since the horses were blinded, it would be up to the humans to convince them to get over the lip of the shelf and into the water, and then urge them through the pool and up the ramp-like formation on the other side to the next level.
"Are you sure you don't want your boots on for this?" Mia asked, grimacing.
The horses, and the men, would be invisible, and the horses blinded entirely. A foot could easily get stepped on and crushed by a hoof in the process.
