At the 2014 Gamescom Trade Show, From Software showed the first official gameplay trailer which gave hints towards some of the Lore in the game. The trailer opens with a long shot of Yharnam and a hint of what appears to be a large, wolf like creature, assumed at this point to be one of the game's bosses. The scene cuts to a shot of a table, with an old man sat in a chair facing away from us. A voice says:
Dear Friend, take heed
The blood is foul
And when night falls
The hunters return
This dialogue is very important. with the "Dear friend, take heed", we can assume the man speaking either is close to you, or feels a kinship with you as he sets you off on your quest. I believe his role is the same as that of the old Firekeepers in Things Betwixt at the beginning of Dark Souls II, a wise sage, or an older character who establishes your reason to be in the world. His warning is stark, but not said in a manner that indicates any fear for your wellbeing, more that he is stating a simple fact that the journey ahead will be dangerous.
"The blood is foul" represents the communicable blight which is at the heart of Bloodborne. It's already been established that Yharnam is in the grip of an endemic plague, affecting people through their blood.
"And when night falls, the hunters return" These lines subjectively states that the game is revolved around the night with an event known as "the hunt" being undertaken.
It's not until the end of the trailer that any further Lore hints are found as the majority of the trailer shows traversal and combat, as well as showing off the art style for Yharnam. At the end of the trailer there is a shot of the player character and what looks to be the old man from the opening of the trailer, observing a building as it burns. It appears that the building could be a church, given it's decoration and shape, it conforms to the European style for a church, but it could also be part of a manor. The area is rural and appears overgrown. Silhouetting the player character is a full moon, leading more weight to the werewolf theory.
As this shot plays out, a female voice says (the voice sounds remarkably like that of the Maiden In Black from Demon's Souls):
And so the nightly hunt begins
Not a lot more information was revealed from a Lore perspective in Sony's TGS trailer for Bloodborne, however there were a couple of useful points to pick up:
At the beginning of the trailer a woman is seen overlooking Yharnam and ringing a small hand bell. The world appears to be at sunset and she is ringing the bell slowly, as if to beckon something forth. She could be beckoning the monsters, or the hunters. The bell sounds remarkably like that of the Octopus-headed guards from Demon's Souls (though that is mostly just a coincidental sound effect use). I believe the woman could be the same one who speaks at the end of the Gamescom trailer, though she doesn't speak in this particular video.
Right after we see the woman with the bell, we are shown a shot of a grave yard with a player character model standing in it. The way the camera pans initially almost hides it, but in actual fact the character is getting up, with an ethereal energy around him. This indicates that the player character is either dead or undead as he is being resurrected. Following this little sequence context free gameplay is shown and no further lore details are hinted at.
The Kirkhammer - a combination sword-hammer - appears to be inscribed with runes. Wiki and forum members are attempting to decipher it here.
