Wisp Keepers
Many times have I played on my good aligned characters and have had no other choice but to go to Dis or the Shadovar to send wisps to people when I had IC reasons I could not send a speedie. And numerous times have I had IC comments: "Why are you dealing with a Fiend? (Wisp Keeper in SV is a Rakshasa.) Oh, you must be evil! Or in Dis: "You're trading with a Devil! You're selling your soul. You must be evil."
Fact is, there are no alternatives (to my knowledge) anywhere on the Surface and plenty of reasons someone could not send a hin.
Wisp bottles
Similar to Wisp Keepers, you can only get these there. Or in Sibayad. In Sibayad and SV however, they are more expensive than Dis for some reason. I would suggest for there to be a vendor of wisp bottles somewhere more accessible on the Surface (Like Mayfields perhaps) and equally priced to Dis.
Gifts!
Chocolates, candy, fancy mirrors, light gem stones, weird looking things you can give a unique description to for RP. These lovely things are currently only available in Dis. Weird and wonderful looking items you can create custom descriptions for and then use for RP and circulate through the world, but is currently not accessible to everyone. And if you are a goodie, well.. Hold onto your hats. You will once more be accused for being evil for trying to create some RP with a unique looking item.
All the above things are great! And would be lovely to have these things available for good aligned characters or characters who would otherwise not have any reason to visit a place like Dis or Shadovar. Being accused time and time IG of being evil because there are no alternatives gets stale real fast.
