[protagonist] was to visit [his/her] relatives in America. After booking [his/her] tickets there was a major incident ([bomb/plane crash/toilet break]?). [protagonist] lost conciousness as a consequence. Upon waking up [he/she] found [him/herself] in what could only be described as an unusual ([jet fighter/swan/self aware sentient being]?) airborne vehicle sat besides a cloaked figure. They spoke in an unknown accent and gender about how [protaganist] was destined for great things and they were on there way to what would be the last refuge for mankind ([and the universe]?). That place was an airborne city, many miles above the Earth’s surface, but undetectable by man-made technology (satellites, radar, spy planes etc).
