(The ending is worth it, look for the crate after Lonesome Road. But dont go back to do the Couriers mile unless your at least lvl 45+ unless you use the flare gun, that will save your life.)
Lucifer got a reply back from Julius telling him about Caesar possition.He also warned Oliver about the legions firepower. 'Since it's not our fight, dont worry about it. We should get going, i'll meet you from what my pipbuck appears to say "The High Road." Once the Legion and NCR are delt with, the victor will face off against Ulysses.' Lucifer sent back to Julius and left the camp to travel to the high road, where many horrors would await him.
