On the very edge of the universe, a small rock floats on the edge of the void. Upon this rock, a small, ordinary lighthouse sits. It had, some have speculated, been standing since the universe and time began. Maintained by a solitary keeper, the lighthouse has been keeping travellers and spaceships from falling off the edge. Its steady beam can be seen galaxies away and is used as a guiding star
for navigators.
