[Castlevania] Why does Dracula always seem to have a motley collection of monsters from multiple religions, mythologies, and continents in his castle?

Dracula is the nexus of all evil the in Castlevania universe. Satan and even Death himself all serve Dracula.

When Dracula awakes, it's essentially the coming of a dark god, and all of the creatures that worship that god are drawn to it. It's kind of like the Hellmouth on *Buffy* opening.
