I should preface this by saying the only Marvel vampire comic I have read is the recent Captain Britain and MI13 arc.
end of spoilers
-Janos son of Dracula is watching a meeting for all sects of vampires held on some Greek island
-His brother Xaros arrives with Alyssa head of the Siren sect
-In the high level meeting with Dracula, Xaros stakes Dracula for his lack of boldness and is helped by the Nosferatu, Trykes and Charniputra (flying and Atlantean vampires).
-He declares himself leader but the leader of the Kriegers(dressed like Germans pre WW1) refuses since the attack was dishonorable. The leader of the Claw ( look like mystical desert warriors) just leave
-Xaros can mass produce medallions that allow them to walk in the day
- The three sects who attacked Dracula , attack the Kriegers in their castle stronghold using the medallions and kill the leader.
-Janos turns to the Claw since he has history with them, but on confronting Xaros with them, it turns out to be a trap since Xaros was working with them from the start.
-Alyssa kisses him and slips him a medallion just as the sun comes up. He uses their surprise that he doesn't burn up to escape.
I am not sure how to use spoilers or whether I went into too much detail. I liked it a lot. I like the world building, especially little touches like Anchorites, isolationists who survive as a farming community who live on animal blood. It is kind of odd that Dracula looks so different but I'd leave it to artistic license. A lot happens in this some nice action and the plot moves forward a lot. The art is also pretty good.
