Siege prologue

Norman Osborn calls a meeting of the Cabal (Doctor Doom, The Hood, and Loki) to discuss Asgard, the last hold out in Osborn's consolidation of power. Namor and Emma Frost are absent due to their betrayal during the events of Utopia, and are replaced with Taskmaster. During the meeting Doom expresses his displeasure with Norman's actions against his ally Namor. Doom accuses Osborn of attempting to kill off members of the group that are not obedient to him, and orders Osborn to bring forth Namor. Upon refusal to do so Osborn has Doom attacked by an unknown assailant. After the attack Osborn examines the body to see that it is not Doom, but a small swarm of robotic insects inside a Doombot. The insects attack the Cabal and under the suggestion of Loki, The Hood flees. Avengers Tower is ordered to be evacuated, with only Osborn staying to attempt to fight off the swarm. When his shields (as the Iron Patriot) are about to fail, Sentry comes in to destroy them. Osborn is later seen talking with the President of the United States to try to secure permissions to invade Asgard under the claim it poses a national security threat. The President does not feel the threat is serious enough to warrant an invasion and orders Osborn to stand down. Loki, listening to the conversation, reminds Osborn of the superhuman Civil War, explaining that it all started with a tragedy in Stamford, Connecticut and that a similar tragedy could be used to gain approval for an assault.
