The nightwalker's lair was a vast cave, roughly the size of two football fields, including the spectator stands. Jagged rocks jutted out in all directions within.
The most striking feature, however, was the enormous oak tree in the centre, so large that it would take ten people to encircle its trunk.
Moonlight streamed into the canopy of this great oak. Within its luminous glow, several nightwalkers were kicking their round skulls back and forth. Others could be seen lurking among the intricate stone pillars.
Although most nightwalkers ventured out to roam, some remained near the big oak. Despite their lack of intelligence, they seemed to possess an instinctual understanding of the tree's importance.
And at this moment...
"Boom!"
An explosion ripped through the air just outside the cave entrance!
The tremor instantly caused every nightwalker in the lair to raise their heads, a flicker of madness igniting in their scarlet eyes!
