No time like the present

You decide to strike as soon as possible as the worm lowers its head toward you, mouth opening to reveal rows upon rows of jagged, ugly teeth. Though you nearly manage to land a bite, the worm is apparently quicker than you are, striking you hard and fast as everything around you abruptly goes dark....

All you remember is the hot blazing heat and then... cool darkness. You awake outside of the chasm on a smooth, flat rock.

A familiar form kneels beside you, tending your wounds. It takes several blurry moments to realize this is not your guide, but a cluster of fireflies in a cloak the same color as your guide's fur. Your injuries are blindingly painful, but you will live; you can tell somehow by the way the fireflies buzz around you. One in particular will stand out, a deep, ugly wound that lies across your left hip, that will leave an impressive scar (about 6 inches long). You feel less knowledgeable at having gone on that adventure as well, losing 52 Navigation skill points.

You realize loosely how little sense that makes and you wonder if this is real, but a warm force closes your eyes and bids you to think of home, of safety. When you awake next, you are in a safe place, one which you might have imagined.

As the worm lowers, you attack. Your teeth meet a piece of steaming hot flesh that gushes a bitter liquid when pierced. As the worm rears, you jump back to the stage.

The worm rolls and screeches, diving into the lava, then into the air, over the stage, and back into the lava. Hot globs of molten rock splash over the stage. Your guide grunts and dodges, his teeth barred in frustration. He glances to you, a silent invitation to take the lead. The worm emerges again. This is it. The final stand!

What do you do?
