Alright, I will explain - or try to. I haven't played MoF yet, I am actually going to be picking it up in a few weeks - but I have watched the entire play through of it, simply because I wanted to know the story. To people who don't understand what is exactly is going on from the first LoS, to this one, which leads hints to LoS2. KEEP in mind that a lot of the things that are unnoticed are in fact from the previous time line. Even though this is a reboot, pay attention carefully - to fully understand LoS you must understand the old series from the NES days all the way up to the DS titles.
A. Gabriel is bitten by 2 demonic Vampire's from the Abyss; He then takes the blood of Laura (the same blood of the Dark Lady.) "You will know pain, -my- Gabriel." due to her purity, and her (laura) being young, this was the 'blood of the innocent' and with her being a child, even though a vampire and with the blood of the queen, she is more powerful that Carmillia. If no one can make sense of it - Laura is in fact the daughter of Gandoffi, its obvious because of the relics and the path that is laid out before Gabriel as he acquires these relics that lead to the demon castle.
"You are betrayed, there is no resurrection, only this living death you see before you!" - the Dark Lady
1. It was never about the God Mask. Listen very carefully to what Zobek meant by "Rule the world, destroy the universe and challenge God himself." and also what he meant by "Reap the whirlwinds scions of death, for here comes the Prince of Darkness."
2. The Gauntlet (Black Knight) - This is in reality, the power of "Death/Zobek", in the ending dialogue, listen to him carefully. "I fought demons and became stronger until a powerful force entered me so vast and terrible." The Gauntlet is actually the "power" of dominion, the ability to rule over all (as said from AoS/DoS) it was then by slaying TFO he (Gabe/Dracul) became the Prince of Darkness.
Hence the old Richter quote "You steal men's souls and make them your slaves." Also, notice how Simon was controlled easily by Dracula.
If you pay attention to the original LoS Gabe is absorbing all sorts of crap with it through out the game.
2. The Mirror "The Dark Lady Watches over you." - Orlox. The three Dark Lords all saw the forecoming of Gabriel through this mirror. After Carmilla is defeated and Pan again tries to riddle Gabriel, look very carefully at the mirror just as he walks through, you will see Gabriel dressed as Dracula. He saw his fate before he stepped into the mirror.
Now, as what Zobek said at the beginning of the game "Darkness has come to claim once proud humanity and we are wittnessing the end of man kind."
There are two Princes of Darkness...
Gabriel and Satan, only one can co-exist.
the Demon Castle - the is the 'Castle' of Hell, the very throne itself in which Gabriel sits upon is Satan's true throne, his "hell" on earth.
My speculation? ---
Gabriel is going to over throw Satan; God is going to be destroyed
Humanity is at the end.
Dracula resurrects every 100 years according to Cox, in the old CV time line, when Dracula resurrected he "had' No memory. Satan resurrects every 1,000 years. Who is the real threat?
The whole purpose is that the Mirror is what destroyed the Belmont clan, led to Gabriel's fall. The only people who did not lie to Gabriel had been the two Dark Lords. Also,
Another thing...
Boba-Yaga - if you see the ending (true ending of LoS) you will see her stalking Zobek. Baba was the only one to 'defeat' death, and she in her true lore stepped through a "Mirror of Fate".
The Toymaker? That is in reality Gandoffi, not his apprentice.
if there is anything else I can think of, I will try to write it down and let you guys know later.
