  In recent years star formation has been discovered in the Milky Way's warp.
These stars formed in the warp (warp stars) must eventually settle into the
plane of the disc. We use an $N$-body$+$smooth particle hydrodynamics model of
a warped galaxy to study how warp stars settle into the disc. By following warp
stars in angular momentum space, we show that they first tilt to partially
align with the main disc in a time scale of $\sim1$ Gyr. Then, once
differential precession halts this process, they phase mix into an axisymmetric
distribution on a time scale of $\sim 6$ Gyr. The warp stars end up
contaminating the geometric thick disc. Because the warp in our fiducial
simulation is growing, the {\it warp stars} settle to a distribution with a
negative vertical age gradient as younger stars settle further from the
mid-plane. While vertically extended, warp star orbits are still nearly
circular and they are therefore subject to radial migration, with a net
movement inwards. As a result warp stars can be found throughout the disc. The
density distribution of a given population of warp stars evolves from a torus
to an increasingly centrally filled-in density distribution. Therefore we argue
that, in the Milky Way, warp stars should be found in the Solar Neighbourhood.
Moreover, settled warp stars may constitute part of the young flaring
population seen in the Milky Way's outskirts.
