We're going to need to find an actual way to open that door since it doesn't seem like someone is going to kick it in for us. Seems like it's not locked with an actual key though, which is probably why my skeleton key idea didn't work. Try collecting some dark magic and doom energy from the all the darkness around here. Maybe we can blast it with enough energy that it will burst open the lock's magic. Stop looking at me like I'm crazy, we have to try something and this is better than looking around for a key that may or may not exist.
This could cause an explosion if we're not careful. I don't need another incident like I had with Valencia a couple of years ago! It's a long story involving a lot moglinberry juice, dynamite, and regret, so don't ask about it. Let's just say she hates my guts and I'm banned from Yulgar's for life. Let's just find a good place to stand back and hurl these orbs of concentrated magic at the door until it opens.
