Abstract
We construct a unitary, modular-invariant torus partition function of a two-dimensional conformal field theory with a Virasoro primary spectral gap of above the vacuum. The twist gap is identical, apart from two states with spin scaling linearly in the central charge . These states admit an interpretation as strongly coupled strings. All other states are black hole microstates.
