Polonius and a number of younger wizards lead them all into a tiled courtyard.  Here they found an elaborate warding circle had been drawn on the floor in salt and powdered silver.<br/><br/>Polonius instructed them to guide their mounts carefully into the circle so as not to disturb the lines.  Once they had all gathered around the arcmage and his assistants had fixed any smudges, Polonius chanted in a resonant voice that echoed like a great bronze bell.<br/><br/>The words were a poem—to those who could speak both the draconic language and that of the angels.  Silver flames ignited the salt and silver, racing out along the ward in all direction, as if the flames were the brightest moonlight.<br/><br/>As the chanting swelled to a high point, then flames coiled around each of them and their mounts as well.  Elaborate diagrams wove around them, including pictographs of celestial language, draconic claw marks, and simply symbols to invoke the attention of the gods...<br/><br/>And then the spell was done and there was nothing left of the beautiful diagram.
