  Einstein's Field Equations have proven applicable across many scales, from
black holes to cosmology. Even the mysterious Cosmological Constant found a
physical interpretation in the so-called ``dark energy'' causing the
accelerated cosmic expansion as inferred from multiple observables. Yet, we
still lack a material source for this dark fluid. Probing the local universe to
find it yields complementary information to the one from the cosmic microwave
background. Could dark energy be sourced by super-extremal charged black holes?
Contrary to intuition, such objects could exist with only weak observational
signatures. The latter are introduced here to outline how sky surveys can
identify individual candidates which challenge Cosmic Censorship on the one
hand but may explain the physical origin of the Cosmological Constant on the
other.
