Reginaldus I's Den

You are walking through long-flooded lands and hear someone humming somewhere from the side. The voice chills you to the bone and you feel a disgusting smell and terrible cold from the direction of the caves.

"The bell has been raised
From its watery grave
Do you hear its sepulchral tone?
We are a call to all
Pay heed the squall
And turn your sail toward home"

As soon as you approach the cave itself to find out where the voice is coming from, something pushes you deeper. When you are about to run out, the only exit is blocked by several ghostly lions, creepily singing the same song that you heard before. But then your attention was attracted by the same rough, but at the same time alluring voice that sang in unison with the ghosts:

"Yo, ho, all together
Hoist the colours high
Heave ho, thieves and beggars
Never shall we die."

You lose consciousness. When you wake up, there are only a lot of lion bones around. You are racing away with all your might, vowing never to visit this cursed place again.
