Warcraft II: Beyond the Dark Portal
Released in April 1996 PC / MAC Expansion Set
Following the destruction of Azeroth's Dark Portal by the victorious Alliance, the orc shaman Ner'zhul took command of the remaining Horde on Draenor. There, he plotted to create portals to other unspoiled worlds and invade each in turn. To enable the rituals for his dimensional conquest, Ner'zhul sent orcish forces through his world's intact Dark Portal in search of powerful relics on Azeroth. Wary of the Horde's plans, the heroes of the Alliance invaded Draenor to end the orcish threat forever. Facing certain defeat at the hands of his enemies, Ner'zhul succeeded in opening numerous portals to new worlds. The resulting magical stress shattered Draenor, trapping many of Azeroth's greatest heroes on Outland, the damaged remains of the planet.
