Mistress Death has sensed that something is amiss, and sends Thanos to investigate. While gazing into the Infinite Well Thanos takes notice of the Blackest Night event in the DC Universe. Recognizing that Nekron, if successful, could potentially "rob" Mistress Death of billions of deaths were he to cross over into the Marvel Universe. This cannot be allowed to happen, so Thanos declares war on Nekron.
