Currently playing through the Black Parade Lore Missions Collection, this is a very simple and short mansion heist with tight security, not only do you have to face guards but also the mechanist security system, mix in some tiled flooring and you got yourself a challenging mission where you have to be tight with your movements and senses. Honestly this mission feels like a filler mission for thief 2, I could imagine it taking place after a stressful or exhausting mission as a way to slow the pace down and get your bearings. There's nothing huge or big here, its just a mansion heist.

Not quite sure what this has to do with TBP, other than having one of the same authors. People keep mentioning TBP lore missions and they seem pretty much nonexistent.
