There are two total Glacial Cavern documents in the game.
The Captain's RevengeEdit
We'll die here, thanks to Carraldus and the madness of the Order of Trinity. My ship will never see water again. We entered the Glacial Sea too far into the winter, would have been turned back, but Carraldus would not abandon this lost Prophet.
He and his dead-eyed warriors seized control. He forced the ship through shallow tributaries, until we could go no further. Then he made my crew construct sled runners, and the bastard forced us to tow the ship over land. It was death and excommunication to deny him.
But it was death either way. I will make sure he dies here, with us. I have always kept a little poison at the ready in case the ship was taken. Now, it has another use.
The captain of the ancient ship prepares his revenge...
The Maria Adula is trapped. The ice gave way, her spine snapped in two.
While I hoped to wield her cannons against the False Prophet, we will continue on foot. I have six of the Order of Trinity's best and we have been stockpiling food and supplies while the sailors starved. They do not know it yet, but they will give their life for the cause. My men and I will find our way out of these icy caves and continue on foot.
Before the ship was swallowed by the ice, to the south, we heard music. That will be our first stop. But first I must rest. The cold has sunk into my bones, and I am drowsy. Just a little sleep...
A Knight of the Order of Trinity pursues the Prophet, undaunted by the obstacles...
