  Intercalated Fe chalcogenide K$_2$Fe$_4$Se$_5$ family exhibits high Tc
($\sim$ 30 K) superconductivity and spin-8 high T$_{\rm N}$ ($\sim$ 560 K)
antiferromagnetism (AFM). We present a model Hamiltonian and suggest
\textit{Skyrmion superconductivity}. A doped electron creates an orbitally non
degenerate S=7\half state in a F$_4$Se$_9$ cluster and moves in a single
correlated band, exchange coupled to a robust S=8 AFM order. Skyrmion, a
topological excitation of 2 dimensional AFM order acquires an \textit{induced
charge -2e} through a quantum anomaly and becomes a Cooper pair.
Superconductivity emerges for a range of doping. Fluctuating superconductivity,
arising from preformed Cooper pairs (stable Skyrmions), around room
temperatures is predicted. We offer hope for higher Tc's in large-S Mott
insulators.
