Also the Bernhard Castle rejects him as master, and he hides away in some isolated church
Per a question that I asked Cox about 2 years ago on his Twitter, that isolated church is actually what's left of the castle.
My guess is that after Dracul was defeated and knocked into a coma, The Brotherhood probably built the church around Dracul's destroyed tower with the intention of sealing him in there.
I think it was said that Dracula has been asleep/in isolation for centuries, prior to his reawakening in present time. So I'm thinking Simon was the last guy to fight & defeat him.
Per Cox this morning, *ALL*of LOS2 takes place after MOF, including the flashbacks. So all those moments in the LOS2 trailer happened after Simon faced him in MOF...and he still looked pretty powerful.
Simon must not have fully succeeded either; if Simon died, he must have had a child before the quest.
