After Event-X, when so many cities were reduced wholly to rubble, Son Lomas became as a city trapped between being and unbeing, whereby it earned the name the “City of Ghosts”.
From a distance the city appears and vanishes in an instant, such that one will perceive either a jumble of abandoned buildings or a shimmering metropolis, bathed in an eldritch blue glow.
If one moves closer, one can see the moving lights of vehicles. Closer still, and the figures of people walking by on bustling sidewalks. If you stand in the right place, you may even be able to hear the city—however faintly.
Some have posited that Son Lomas is trapped inside a rudimentary time-loop, whereby its inhabitants are doomed to live out “the day before” in perpetuity. It seems more likely, however, that the city continues to experience linear time.
We simply do not know how.
