Whats there?

Beneath me the sea reared. Fog swirled though the air. In the distance, just visible through the clouds, lay a castle so grand it would have put the entire population of Rome into shame. As we trundled along I looked at him, his face was as white as a sheet and his eyes sparkled in the gloom. Splashing under our wobbling cart, the ocean leapt and bit with its ice cold power. The castle grew clearer and clearer through the cold and the waves. Though it seemed pointless, I kept thinking if there was an answer it would be there.
