We consider N=(2,2) AdS3/CFT2 dualities proposed in the large central charge limit (c→∞) by Eberhardt. Here we propose the associated D1-D5 systems to be orbifolds of the standard N=(4,4) systems, thereby elevating the dualities to the finite-c level on the boundary and to the quantum level in the bulk. In particular, we show that our brane systems yield low-energy sigma models whose subleading central charges match earlier predictions from bulk one-loop supergravity computations. In the case involving the Enriques surface, the finite-c sigma model has a non-trivial elliptic genus which we use to microscopically explain both the Bekenstein-Hawking entropy and the subleading logarithmic correction to it for the associated macroscopic black brane.
