Once there, a time anomaly hurls them back in time 10 thousand years into the past, at the dawn of the War of the Ancients. They try hard not to get involved, but unbeknown to them an orc had followed them. What happens when Mannoroth faces a time-displaced orc … Will the presence of an orc in the past alter time forever?
