Karl raced through the darkness, following the sounds of snarling and crashing towards the heated battle. Then skidded to a stop when he saw the situation.
Cara was squared off against a tiny ball of glowing fur, with a large shining rock in its paws.
She cast [Void Blast] and the fur ball surrounded itself with a rock shield, then pelted her with spears of holy light, which she blocked with a barrier of [Disintegrate].
That made the spears explode, and the cavern trembled.
They were attacking multiple times per second, and the whole cavern complex was trembling.
Karl shaped a [Bulwark] to trap the furry creature, cutting through the stone to put it in a full bubble, and the battle stopped.
"Cara, what is that?" He demanded.
[It stole my rock.] Cara complained.
Karl paused to take in the room. There was a nest of soft dirt, the body of a long dead white fox, which felt as if it had been incredibly powerful when it was alive, and then the furry thing with the shining stone.
