The journey to the site was not easy. Many areas were unstable and would collapse with the slightest step on it. Visibility was zero due to the thick smokescreen from gases and explosions.
"We have a two-hundred mile stretch between us and the device. We will need to stop every few miles to rest a minute.", Celestia said as she led the way.
They marched over the ruins of Equestria and the lands beyond, stopping to rest every few miles. During their rest breaks, they put up a shield in order to take off their helmets so that they were able to eat or get a drink. The journey through the ruined land was harsh and they ran into many obstacles. For instance, they sometimes had to shimmy across cracks and take running jumps over sinkholes. When climbing over mountains, they were battling strong winds and drastically high amounts of turbulence. There were three times that they almost fell into lava, but they saved themselves with grappling cables.
Two weeks later...
They finally started getting a readout on their scanners. They were only nine yards away from where the device had been placed. Arriving at the device, they began to power it up. Little did they know that a storm was approaching rapidly. After they set the device to resurrect the planet, they started setting the timer. Suddenly a lightning bolt shot towards the device and zapped it. The timer mechanism malfunctioned which would cause the device to detonate prematurely, but they still had approximately enough time to escape. Realizing that the device would detonate in five minutes instead of five hours, they made a run for a high hill nearby with a relatively flat peak.
