Synopsis by Hal Erickson
Eric the Red, emissary from Shi'ar, takes over the Eagle One space station. Eric's purpose: To clear the path for his emperor D'Ken, who is determined to destroy his sister Lilandra and gain control of the M'Kraan. And if the X-Men should try to interfere, they may be crushed by space gravity. "Sacrifice" was a continuation of the story arc launched by the two-part X-Men adventure "Out of the Past," and the inaugural entry in the series' multipart "The Phoenix Saga."
