  This article investigates pathological behavior at the first limit stage in
the sequence of inner mantles, obtained by iterating the definition of the
mantle to get smaller and smaller inner models. I show: (A) it is possible that
the $\omega$-th inner mantle is not a definable class; and (B) it is possible
that the $\omega$-th inner mantle is a definable class but does not satisfy
$\mathsf{AC}$. This answers a pair of questions of Fuchs, Hamkins, and Reitz
[FHR15].
