  We generalise the hyper-Kahler/quaternionic Kahler (HK/QK) correspondence to
include para-geometries, and present a new concise proof that the target
manifold of the HK/QK correspondence is quaternionic Kahler. As an application,
we construct one-parameter deformations of the temporal and Euclidean
supergravity c-map metrics and show that they are para-quaternionic Kahler.
