Guardduties at the border area between Yakyakistan and Equestria.
The Batpony Night Vision has to keep vigil here in a remote region and watch out that the yaks stay on their side of a valley. Normally he wouldn't be alone, but due to an accident that caused a comrade to return badly wounded and he couldn't have done it on his own, Night Vision now has to get by for one night.
it's good for him when he has company, but it's strange.
There shouldn't be anyone out here except for him and his squad
