The teleport stone should simply take you to different locations without explanations, It's up to the player to discover what lies at the other end.
If your server is into the role play style then you could have a notice board NPC or server guide NPC that lists areas and describes Oma caves as a great place for new warriors to learn their trade etc., or Wooma Temple is a tough place suitable only for experienced mirians...
I wouldn't have all the explanations and scene setting on the teleport NPC though.
