Deep within the forest, inside a hidden cave covered in vines and moss, the air was damp and cold. Water seeping from the stone walls slowly dripped along the cracks, its dull patter breaking the deathly silence.
A vortex abruptly appeared in the center of the cave, tearing a distorted rift through the air. Then Obito tumbled heavily out of it.
Thud-!
