Today's is "Stairs".
There are TONS of stairs across the lands of Azeroth. The set of stairs pictured above, however, are the ones that stand out the most to me.
This staircase is inside the dungeon Zul'Farrak, in Tanaris.
This used to be one of the most daunting dungeons for me to run way back when...and this staircase event was the worst part of it. It was the first gauntlet-type event I had ever experienced...and died during many times. But, it was also one of the most fun fights I had ever encountered.
It's one of those "love-hate" relationships I have with this staircase.
