Sweet. This gets more zetta interesting the more he explores. He double taps his badge. "GIVE ME REASON!" And when his familiar appears he shows it the marking. "See if you can find any more marks like this," he ordered. Then he started gathering rocks and fallen branches, bones... any detritus he could find and while his familiar is hunting for other sigils, he's making a monument off to the side at the base of the bridge. Art for whoever comes next... and a landmark to find his way back.
