I seek entry to the Hidden Halls

[Harry Dresden]

So, after the Rathalos event is over, Harry's going to be setting up his base underneath the abandoned city of Edinburgh. The ruins are in one of the mountains near Minas Tirith, with the castle partially built into the mountain. The city was summoned up by someone with a penchant for Scotland who got stuck in the Omniverse, and (not sure if I'm allowed to do that) served as a covert base for Diablo's forces before they were banished to the Underverse. Harry doesn't know that. He'll recognize the city and seek out one of the tunnel entrances, finding an unfinished tunnel project. He'll probably set up a ritual to finish them to something similar to the Hidden Halls from his own universe.

Does anyone want to interact with him at some point? Maybe they know about Edinburgh and want to use the city as a place to regroup after the Rathalos fight. If they weren't involved, maybe they meet him at the gate? Could be beneficial to get to know a Warden of the White Council. That, and Harry has no idea what's going on, so someone to explain things while he preps the ritual to summon the finished tunnels would be sweet.

[Ganondorf]

I had considered it, but I doubt Harry would be able to put up with Ganondorf for any period of time where they'd live together. Also, Ganondorf has his own designs to follow.
