Yo thanks!!

Go to vaati Vidya's channel you'll find literally everything about bloodborne and the souls borne series

I looked at that graph a little more closely, it implied lauerence took the blood to Cainhurst and got funding. Dont recalled ever seeing that mentioned in the game. That is the author personal interpretation.

Never mentioned who. But guess it's simpler to say Laurence but that just seems odd in my book.

Well, the burning of Old Yharnam had to have happened pretty recently before the game considering that there are still burning crucified beasts and fire pyres.
