Lomax is a Seeker from the New Order, sitting on a stool at Jackson's Farm. He is level 5.
When sitting in front of Jackson's barn: "Oh Elisabeth, if only I could win your heart!"
From this you learn he has a crush on Elisabeth that can be used in the quest Feast or Famine. If you choose the option this unlocks then from then on Lomax can be found pestering Elizabeth with bad attempts at romantic pick-up lines.
During the quest Saving the Bacon when he returns from the distraction: "Slayers… They think they're so much better than everybody else!"
This can only be read before you complete talking to him, but doesn't unlock anything.
