The plan was actually more easy as the vaults were 'clearly encased' in rooms, which would help facilitate the portals to the actual storage. He had been half afraid that the 'main common area' was all there was, and he needed a special key from multiple people to get into the second area, which would connect to the various vaults. Since they hadn't been THAT paranoid, he actually could discard a piece of his plan. Of course, if they had been, the vault's location would have been obvious from orbit, due to the massive amounts of magic needed to make it, so maybe it was better this way.<br/><br/>But there would be a sort of 'master key' that could open all the 'vaults' if only so the Fae could get items from them without needing to get the specific key to the vault first. Likely, it was based off the magic of the Winter Court, and while he had its opposite, it couldn't be inverted to duplicate the master key. So he would have to break in, defeat the personnel inside before his initial distraction faded, then break into each vault he could, before finally getting out. Since he was trying to make a statement with the hit, he would have to avoid killing or even knocking out people, though since the people were drow, he knew they would cheerfully butcher each other for giggles if they thought they could get away with it. Since it was his intention to abuse that nature to gain entry to the first room, there would be a body count.<br/><br/>He also did some research into the city the vault was located in, specifically how big of a cavern was it in, was it divided into multiple caverns, how many drow, how many houses, things of that nature.
