  We construct new examples of torsional heterotic backgrounds using duality
with orientifold flux compactifications. We explain how duality provides a
perturbative solution to the type I/heterotic string Bianchi identity. The
choice of connection used in the Bianchi identity plays an important role in
the construction. We propose the existence of a much larger landscape of
compact torsional geometries using string duality. Finally, we present some
quantum exact metrics that correspond to NS5-branes placed on an elliptic
space. These metrics describe how torus isometries are broken by NS flux.
