The young man feels the surge of physical power, wondering at it. Magic. Must be trained... He shakes his head. Can't focus on that now... Must get free. Must climb.
Fighting against his weakness, real or imagined, he knows not which, Jareth grips the chain and struggles, lifting himself past the former limit of his strength. He feels as though his arm will give out, tear away, pull itself free from his shoulder and body, sending him cascading through the darkness below. His legs and pinned right arm scream in protest, trapped in the unwelcome embrace of the stones. He pushes back the urge to cry out, knowing he must endure. For himself. For his purpose. For Tharivol's life. For his own family...
The thought once again brings old memories to the surface. He brushes aside the face of his father, focusing on his mother, brother and sisters. He knows he must get free, find them, save them. With a growing growl, he pulls harder on the chain, ignoring the agony of freeing his trapped limbs. With an increasing sense of power and sureness, he makes his way up the chain and crests the edge, heaving a mighty breath after pulling himself over. His face still pressed to the slope, he mutters a "Thank... you..." between gasps.
