Saracen Rue was one of the nine members of the Dead Men during the War.
At one point Saracen also dated Tanith Low. While Saracen was dating her, the two fought together in a battle. After the night was over, the two kissed under the moonlight, drenched in gore and pieces of brain. Tanith recalls it as a "night enjoyed by all"
He also participated in a mission in Siberia to assassinate the Butcher, a soldier so terrible his own wife and soldiers disliked him. Saracen seduced his wife and hid with her for three days until his ankle healed.
He also went up against Baron Vengeous in Leeds, and the psycho Sisters, Cerys and Aspen in Norwich. He also seduced them, but not at the same time.
In The Maleficent Seven, Saracen made an appearance as one of the six people that helped Dexter Vex search for the four God-Killer weapons. It was shown that almost nobody knew what his magic was - when asked, he simply replied that he "knows things".
Apart from that it was Adept, all that has been said about Saracen's power is that he "knows things". He demonstrated this when, for example, he knew that there was a guard around a corner holding a machine pistol without seeing him or hearing him.
When Derek Landy was asked about his sexuality, he responded that there was none when one was 400 years old.
