Dilan dashed straight toward the huge crowd of Vampires. They could clearly sense that Dilan was the one carrying the five Sanctum keys with him, which was why all of them began to charge at him.
The huge crowd of approximately 1800 enemies was hurtling towards his direction, slowly closing the gap they had kept between each other to make sure that nobody would assume that they were working together.
Vampire Clans were strict about making clear who they had joined hands with and which Clans weren't in an Alliance with them. The four Vampire Clans in front of Dilan didn't hate each other but they wouldn't usually work together either.
It was merely good timing that the four Vampire Clans had arrived in front of the Sanctum of the Old Vampire Lord roughly at the same time and that their traveling speed was the same as well.
This was unexpected but none of the Vampire Clans wanted to lose out to the others, which was why they didn't even think about slowing down.
