Welcome to Ask a Lore Nerd, where each week Alex Ziebart answers your quests about the lore in the World of Warcraft. If you have any questions, no matter how big or small they might be, ask them in the comments section below and we'll try to answer it in a future edition.
Let's get this party started with Lionheart's question...
What is that barred off instance looking portal thing in Stormwind, by Old Town? Were the gates once open?
There are actually two of these in Stormwind. Neither of them were ever open, they're relics of unfinished projects. One is a closed off little guarded island in the Canals. That one was going to be the Stormwind Vault, probably a dungeon like Arcatraz or the upcoming Violet Hold in Dalaran. Probably.
There's also the barred off one at the end of the Canals, right down the way from that one. This is probably the one you're referring to, I'm going to guess? I don't think we've gotten a real answer on this was supposed to be, but it was probably going to be the portal to player housing. They actually did start work on player housing at one point, but never got far. There are relics of it in the game files. Half completed houses/structures, things like that. They all use the Stormwind motif for their appearance, and they would have to put it somewhere. Through this portal is a safe bet.
Jaina Proudmoore and Arthas. Any chance they'll hook up against in the future? What are the details of their history together?
