Rooper could see what she had to do. With Silandra slowing the tide of creatures coming up from below and Rok defending the steps, Mittik and the others needed Rooper's support at the alcove.
She took a running start and leapt into the chasm.

Silandra had been doing - ducked to the right, swerving Rooper's jump so she missed her anticipated footing and tumbled past, arms wheeling.
For a moment, she felt as if the entire world had fallen away beneath her and she was simply going to drop and keep on dropping until she hit the bottom of the shaft.
But then her feet struck something solid - the outer rim of Silandra's shield, which was hovering beneath her in midair- and she was springing up onto the back of one of the shrieking monsters, riding it back up the shaft toward the morass at the top. She caught Silandra's eye for a fleeting moment, and then her master was gone again, lost amid the thrashing limbs of the beasts.
