Someone told me that Alpha Lupi is one of the traveller's names. In this case this is conveying that the Traveller itself feels like it's being pushed by its pursuers. Personally I think the Traveller seeds light into sapient races and they grow reaching a golden age. people with light have it grow within them, and after people die the Traveller pulls the light back in. Sort of a symbiotic relation. People have found that in the grimoire that when Rasputin detected the Darkness it deleted its morals and had only one goal left; to win at any cost. Rasputin then allowed for almost all humans to be wiped out, if what I said above is true then this would give the Traveller tremendous amounts of light, but other cards hint that the Traveller tried to escape, and Rasputin crippled it to prevent this from happening. Perhaps the Traveller thought the battle was impossible and decided to go out and find a new civilisation to arm for the battle against the Darkness, idk. The Traveller after pushing back the Darkness then created ghosts, a new thing that gave people filled with substantial amounts of light the ability to come back from the dead.
