Having heard these words of the royal maid, the hunchback became furious and speedily descended from that palace resembling the peak of mount Kailasa.
— M.N. Dutt (1891)
Manthara hears the news and is consumed by fury. She descends from the palace like a force of nature — speedily, irresistibly. The hunchback's descent from the palace is the turning point of Ayodhya Kanda. Everything that follows flows from this moment.
