Dimensional reduction over time is a useful method for constructing stationary solutions in supergravity, both extremal and non-extremal. For theories with N=2 vector multiplets one can in addition exploit the special Kahler geometry encoding the couplings. I will explain why aformulation in terms of real coordinates and a Hesse potential is useful, and how special Kahler geometry is related to
para-quaternionic Kahler geometry by dimensional reduction. As an application I will present the construction of black brane solutions with vanishing entropy density at zero temperature (`Nernst branes') in FI-gauged N=2 supergravity in four and five dimensions.
