For about a decade it is known that topological fluctuations -- instantons -- are modified by the nonzero Polyakov line VEV and split into Nc dyons. By now there is extensive lattice literature confirming this fact and explaining certain observations by properties of such dyons, mostly at T=(1-2)Tc. This talk report the first direct simulations of the statistical mechanics of the ``dyonic vacuum", using one-loop partition function. We found that chiral symmetry breaking and Dirac eigenvalues spectra are strongly affected by the LLbar dyon clustering. Among many consequences explaining lattice data is the dependence on the chiral transition on the number of fermion species Nf and the fermionic periodicity condition.
