This works best if you have a caster that can gate (bind at Nestral or Rebby) but next best would be a bard with Selos. It's just running back and forth from East Freeport to West Freeport.
Do this quest over and over. The quest reward (Rebby's Whiskers) is not lore and stacks to 20. You can sell them in EC for 5-10pp each for lazy people trying to fix faction. You should be able to make 100-200pp an hour.
Make a hotkey for the dialogue:
For Nestral: I can run to Janam and Rebby's
