From the introduction:
Tripping up each step, the wyverstones pulsing and shimmering around you, you break to catch your breath. The howling wind warns you to stay off this next path - an arduous balance across a thin bridge of stone, with a plummet to sharp crags waiting beneath. But it is the only way forward, the only way beyond the grasps of the Crimsonclaw Wyvern that has been on the hunt for the past two days.
Your comrades apparently weren’t enough to sate its belly. Steeling your resolve, you press your first foot into the stone, testing its strength. Step... step... step, ever forward you creep blasted by the tumultuous winds, until at its midpoint, a screech rings above the rush of air. There, careening through the clouds above you, its massive black and red form almost a blur, its six burning yellow eyes locked on your position. You remove your spear and your shield…for a final stand is all you have left.
