http://everquest.allakhazam.com/db/faction.html?faction=673 The chetari and the undead around the wizard port in spot for ROS Skyfire are on the Vampire faction. Apparently there is no way to raise this faction. I started out non-kos here and I have been careful to remain not KOS. But almost everyone I port in here is KOS and can't seem to survive the ordeal.
I agree, I don't understand why they thought putting the wiz port in at that location was a good idea.
I would be very happy with either solution. Perhaps an alternative: Make it so there is a KoS NPC at or near the port in location. Faction with that NPC is tied exclusively to progression within the expansion. For example, once the PC has completed Skyfire progression in RoS, the NPC changes to indifferent faction.
If the faction does nothing else... it could be the silliest of quests for a huge faction boost. Make it story-lore-goofy.
That's the worst answer. It's right, but also wrong. There's no good reason for the difference anymore.
