now I can fly around

You decide to use the bridges. They seem to have stood the test of time, being singed here and there. They're easy to cross, and you progress steadily until one snaps out from under you. You scramble at the surface just enough to save yourself from falling in with a little help of the guide. The lava sputters, splashing you across your right ear. The lava singes through your fur, leaving a deep burn across most of your ear. Ouch! that's gonna leave a scar.

Across the lava room stands a flat piece of smooth stone, so level and flat, it is as if thousands of paws had worn it over time. It looks cool to the touch and vaguely important. Surrounding it is a mote of lava, separated only by sharp stalagmites that impale it to point towards the open ceiling. There is no discernible path across. You know you must get there one way or another, but you're not sure you'll be able to go back the same way you came if you cross.

What do you do?
