Unknown Dungeon

The Unknown Dungeon (also known as the 5th Door) is last Dungeon in the base game Moonlighter. It is only available after having defeated the Bosses of the other four dungeons as it requires their 4 keys to be unlocked.

Lore
"Body prototype development from other dimensional tech is proving successful. Each variation seems to have a lower percentage of body rejection."

- Dimensional Pirate(?)

"This next set of dimensions are looking to be very promising. With enough synthetic and natural resources from them, we can start Prototype G."

- Dimensional Pirate(?)

"Reports indicate the Watch are on our trail. We may have to seal ourselves away to mask our signal."

- Dimensional Pirate(?)

"We have been forced to enact Operation Lock The Door. The minion is to shut ourselves in using 4 keys. It will then hide those until the Watchers stop looking for us in this sector. We predict a month should be an adequate amount of time to lose them."

- Dimensional Pirate(?)

"It's been over two months since we shut ourselves away in here... Resources are running low... Where is that minion to set us free? Meanwhile... we started development on Prototype L."

- Dimensional Pirate(?)

"That stupid MinERROR"

- Dimensional Pirate(?)

"Escape from this tomb seems to be fading away as a possibility... 3 months going now... our soldiers had to put an end to some riots last week. We need to find a way to escape."

- Dimensional Pirate(?)

"This is getting out of hand. Several coworkers went mad and were instantly killed by the soldiers! Two problems solved with one solution... The riots and lack of food..."

- Dimensional Pirate(?)

"Ignoring the problems brewing, we have nearly finished Prototype L's chamber. The boss really wants to try the new body, but we are unsure if it's safe yet."

- Dimensional Pirate(?)

"Prototype L is finally fiERROR"

- Dimensional Pirate(?)

"There is only (one) way to escape. Supercharge the dimensional engine. Crash into another dimension. Or crash the void. Anything looks better than starving to death!"
