Question about faction
 

I'm trying to become not KOS in freeport with the good factions as a dark elf, but the Arcane Scientists(http://wiki.project1999.com/Arcane_Scientists) are still KOS. This is kind of a problem cause I'm also KOS in the sewers, and I want to be able to train with the enchanter and buy spells in freeport. I know I can use illusions, but I was wondering is there any way to raise my faction rep with the Arcane Scientists through mob killing/quests?
