If the Traveller was once an ally of the Eliksni then did it grant them use of its light or create ghosts for them? And if so what happened to their ghosts and Lightbearers? Is Mithrax an Eliksni Lightbearer? I wish I could play as an Eliksni. What about the possibility of Diplomacy with the House of Light or Variks new group?
No. The traveler only created ghosts after the collapse.
