Looking for a Victorian supernatural PnP

Hello boardgame community! About a year ago I briefly came across a PnP Ruleset that I found very intruiging, but I cannot find it anymore. Also not on google withaforementioned keywords, so I hope you'll be able to help me out.

Here's what I (think I) remember:

• It's set in a Victorian era-
• The players are under the command of the queen and have to fight the supernatural
• They party has a shared resource pool that the have to assemble beforehand
• If the players prepared wrong they have to abort the mission and try again in the next session
• Maybe there was something about magic corruption?

That's all I can remember, I hope you guys can help me out on this one! All hints are welcome!

P.S.: I'm quite sure it is not candela obscura, as this has not been made public at that time.
