The Adventurous McGurn

You know there is only one thing you can do and leap backwards, drawing the stumbling ghast towards you.
It leaps, but you deftly step aside, and thankfully the clouds above roll aside and the fading sun shines through.

The ghast wails, caught in direct sunlight, and scurries back towards the hole in the ground you spotted earlier.
You try to catch it but it's long legs carry it away and it swiftly topples into the hole and disappears.

You may have left adventure behind but, it seems, adventure has caught up with you.
