King Parikshit had a son: Janamejaya.
One day when King Parikshit returned from hunting, Janamejaya saw he was dismayed. "Father, what troubles you?" he asked.
"I am cursed to die within seven days of snakebite," Parikshit replied. "In the forest, I entered a rishi's house. I greeted him, but he said nothing. That made me angry, so I draped a dead snake over his shoulders. The rishi's son saw me do this and cursed me."
"No!" Janamejaya said. "We will protect you."
They locked the king high in a tall tower. No snake could reach him, or so they thought.
