During this time, Xanatos took on Owen Burnett under his wing, a former employee of business rival Halcyon Renard, as his assistant. Eventually, Burnett revealed that he is actually Puck, a Child of Oberon, and offered Xanatos a tempting choice: a single wish (which could grant the immortality he sought) or a lifetime of service as the mortal Owen Burnett. Against Puck's expectations, Xanatos, confident that he could achieve immortality through other methods, chose Owen's service, and the decision deeply impressed Puck to keep his end of the bargain, with the inference that, should Xanatos achieve his goal, he will be guaranteed Puck/Owen's services for eternity.
