  We study Heterotic supergravity on Hyper-Kahler manifolds in the presence of
non-trivial warping and three form flux with Abelian bundles in the large
charge limit. We find exact, regular solutions for multi-centered
Gibbons-Hawking spaces and Atiyah-Hitchin manifolds. In the case of
Atiyah-Hitchin, regularity requires that the circle at infinity is of the same
order as the instanton number, which is taken to be large. Alternatively there
may be a non-trivial density of smeared five branes at the bolt.
