He has an idea! The ground beneath his feet feels soft enough that it could be dirt. He manages to find a small handful when he couches down, which is just perfect. With a quick wave of his other hand he draws water into existence and directs it's form into a small tray before solidifying it into ice. After dumping the small scoop of dirt into the tray, he magically adds more water so it's a nice muddy mess - more water than dirt really. That's what will allow him to read what Regis writes though.
