Always shocked and appalled that no one has ever made a Metalocalypse version of one of these "[fantasy/fiction media] ambience music for studying and relaxing" things.
I would give an arm and a leg for a Mordhaus ambience. I would work so hard listening to it you don't understand. I wish I had an ounce of audio editing skills but for now I can only make this shitty fake screengrab
Here's what I think it would sound like
hollow-ish sounds of a cave-like place
echoing hallways
crackling from the fireplaces and torches on the walls
a very low church-like organ to really bring the medieval castle vibes together
muffled voices coming from another room (lines from the show said by the guys, Charles, Dick, Abigail and various Klokateers)
nearby thuds and bumps from the Klokateers working around the place and dying and stuff
maybe a single distant gunshot at some point
ocassional and distant gregorian chants maybe? from Black Klok church services or Klokateer initiation ceremonies perhaps
steps from Klokateers walking on the stone floors. some nearby and some farther away
large heavy doors being opened and closed plus the creaks from the hinges
muffled guitar riffs and other instruments (possibly even parts from Dethklok songs) from the band fucking around in the recording room
ocassional distant yelling from Klokateers screaming in pain and from the guys bickering between them, just to keep it canonical lol
I have only achieved a slightly similar vibe by playing a D&D cave ambience on youtube and a church soundscape on myNoise but it is REALLY lacking the characters' voices and sounds to tie it all together
