Ethan Rayne is a foe to Rupert Giles and is portrayed by actor Robin Sachs. The two were friends who met in London after Giles had dropped out of Oxford. The group practiced small magics for pleasure and gain, until Ethan and Ripper discovered something bigger: the demon known as Eyghon, or the Sleepwalker. Tattooing themselves with the Mark of Eyghon, they would take turns falling asleep, and the rest of the group would summon the demon into the sleeper. According to Giles, it was an extraordinary high, a euphoric feeling of power, but was also incredibly risky. When Eyghon took control of Randall, one of their group, the others tried to exorcise the demon, resulting in Randall's death. Giles was changed by the event, leaving London and returning to the Watchers' Council. Ethan, on the other hand, went in the opposite direction, delving deeper into the black arts.
