Time Splicing of the Dark Portal

Note: ''This is a placeholder document that anticipates the upcoming plot in the Warlords of Draenor expansion. The events of this have not yet occured in Azeroth.

Reasoning of the Time Splice
Garrosh connected the Dark Portal to an alternate parallel universe, bridging his own universe with that of a parallel universe whose orcs had not yet drunk Magtheridon's blood. Thus he did not alter any history of his universe.
