Lore
As if awakened from the most terrible dream, the warriors' eyes opened together. Dazed still, they tried to recall the moments before. Their ship capsized, they had hopelessly drowned in the icy depths of the ocean, merciless reaper of lives. But now there was a ceiling over their heads. A ceiling of a rapturous beauty, ornated with the most delicate engravings.
They looked at each other, at the salt that crusted their bodies, and at the seaweed and coral that protruded from their armour. With parched throats, cracked lips and wretched faces they looked at Odon, their burly captain, as he slowly rose. The salt in his armour crunched as he moved, as he thrust his halberd into the clammy stone floor. He looked silently at them in turn, gaze hidden behind his impervious mask. He knew where they were. This had to be the cathedral that the Miracle had long hidden under the dark waters of the sea. Salt had granted them life, and he knew his new orders were clear. To guard this sacred place, and to do so until their deaths. Death they would not fear, for they had already conquered it once.
