Once on Ravnica, they discovered that planeswalking away was impossible. The Immortal Sun suppressed their only reliable escape.
The trap turned a city-plane into a closed battlefield. Experienced heroes, opportunists and walkers with no connection to the Gatewatch suddenly faced the same threat. Some possessed extraordinary magic, but none had prepared for a war in which every spark made its owner valuable prey.

The people most likely to die had never chosen to enter Bolas's game, which gave the visiting planeswalkers a responsibility extending far beyond their own survival.
