I understand our friend Beaumont´s situation. The whole story of LoS is in times complex and plot-twist in the end (thanks to Kojima, I believe). The stuff with the masks was Cox creation. I remember that in the begining, he said that masks was important part of the Castlevania lore... well, aside from the Carmilla mask in Simon´s Quest and Dracula´s mask in SCVIV, I don´t know of other games wher the masks were an "important part" of Castlevania (Maybe the Dracula´s third form in CVA Rebirth...).
I play and finish the game a few months ago, and I find the Zobek dialogues a little tired... in fact, at the final chapters i prefer to skip it when the combat cross/loading was full, and the same to the messages of the fallen soldiers (I don´t remember his names). In resume, I simply don´t like the LoS history, but, as always, it is my opinion...
...I remember the old times, were the whole plot was to enter the castle and kill Dracula...
