“I didn’t have to wait long to know what she meant. About ten minutes later, as we crouched in the cover of a broken sales bench, the pale grey light from the clouds was blotted out by the massive form of a black, anvil-shaped Enclave mobile fortress. Four great thunderclouds spanned out from it, two on each side…The undercarriage of the massive ship bristled with weapon turrets. I could make out several large doors capable of dropping war chariots or bombers or troops by the scores.” - Fallout Equestria
