Blood Moon Nocturne

A long time ago, the world nearly fell into total darkness.
The Lord of Vampires, Count Vlad Dracula Tepes, sought to rule the world and exterminate the human race. To aid in his war he created an army that followed his every command and obeyed his every desire.
Alongside him was Carmilla, his Bride as well as her group of devoted daughters. She worshipped Dracula and sought only to serve him.
Out of an enchanted castle in Transylvania the Dark Lord carried out his war against humanity. His plan was to use a magical artefact of great power known as the Crimson Stone, a gem that connected all children of the night, in a rite known as the Blood Moon Ritual that would grant him incredible power. However, the church as well as a brave band of hunters and magicians managed to infiltrate his castle and confront him. They defeated him and shattered the Crimson Stone before the ritual could be completed. Carmilla and her family managed to escape, vowing revenge for her lover's defeat.
Knowing that there would be others that would desire to complete the ritual and return Dracula from the grave, a powerful magician scattered the shards of the Crimson Stone across time, space, and even other dimensions in order to keep Carmilla from acquiring them.
Hundreds of years pass and the fragile peace brought by Dracula's death is close to ending as Carmilla has returned to the castle and is carrying out her plan to restore her lover and finish the blood ritual.
If she succeeds, the world will be plunged into endless darkness and death.
All that stands between her and her plan is a select group of unlikely heroes from different dimensions, all brought together by their ties to the night...
