Many of us have stepped through the Dark Portal into Outland, and in that time dozens of players have mastered the content available there. Now that we have BlizzCon in our sites, all eyes seem to be on what our next expansion will be. As Chris Metzen mentioned at the last BlizzCon, Outland is peppered with portals, each with the potential to open another world for us to explore.
I personally know of two such dead portals, empty and devoid of life. The first is in Zangarmarsh, at the appropriately named Portal Clearing, and the second is in Nagrand. Have you found any other portals in your time in Outland? If so, do you think that the locations of the portals could be a clue to what lies behind them? Going with this theory, we might postulate that the Zangarmarsh portal might lead to the Maelstrom, since that zone is riddled with naga. What do you think?
