The stench of Demons was all too familiar to Cedric. And because his home was near the outer edges of the city, his field of senses caught sight of them earlier than everybody else.
Just a reminder, these aren't Purgatory Demons. Killing them won't reward them with Demon Souls. These demons however are the real deal, and they're deadlier than their Purgatory counterparts.

"...ah! So that's why there's a Lighthouse there." Cedric was suddenly enlightened.
