Judging from the responses so far I don't think what I created is Castlevania, though it was initially intended to be a homage / inspired by, Castlevania.
Without giving away a whole lot of detail, what I created features the Belmonts, features a variety of Vampires, Mummies, and other supernaturals, Features death, it features the castle itself, but it does NOT feature dracula.

In the year 2025, the world teeters at the brink when Castlevania, the Castle of Dracula, suddenly appears in Mid-Air over the capital city of Bulgaria. Dispatching heroes to stop the certain-to-ensue carnage, the world calls upon an elite squad of vampire hunters, in the pay of the Vatican, led by Theodore belmont. Theodore and his group are able to penetrate the castle and square off against its horrors before things get really bad for the outside world, however, one of the people in the squad, is the REINCARNATION of shaft. Not knowing this, she (yes she), is exposed to energies which cause the old submerged personality to re-emerge suddenly. Ultimately, this results in Dracula opening a -very large- portal to the netherworld in desperation. Unfortunately, the demonic denizens of the netherworld think that the gateway is created by the four horsemen, and, due to this misunderstanding, attack with full force, expecting an earthly army to be there lead by the four. Their conclusions are wrong however. In retaliation for this perceived insult upon his domain, Death causes every germ weapon in the entire world to explode. All at once. No matter where they are, no matter what is being done to them. (even the ones that are undergoing disassembly for repairs suddenly explode).
...400 years later, humanity now finds itself in a strange and savage land ruled over partly by humans and partly by supernaturals. The ruins of the castle, impervious to time, age, or wear, now sit in one area and do not travel. Dracula has died for the final time, and won't be making an appearance.
