My own wish-fulfilment fanfiction because I can. Cuan Bryan. A young woman from a single mother of Scottish descent yet Cuan looks Greek. That's because her father is the Greek God Poseidon. Lord of the Sea and Bringer of Storms. The Earthshaker. What happens when she shows up just as Castiel becomes overcome by the Leviathans he swallowed up from Purgatory?
