Tales and Chronicles
Jewel of the North, formerly know as vincegetorix
IIRC in 4th edition Vistani were described as a plane hopping culture, traveling around the planes...
Yep, just remembered, from Dragon 380. Plane hoping culture that welcome any travelers as part of their own. In the art, you add a dragonborn vistani and a tiefling vistani.
Really cool stuff. They were primarily traveling between the ''echoes'' of the world, so the Shadowfell and Feywild.
So 1 ''Vistani guide to the Shadowfell'' and 1 ''Vistani guide to the Feywild''. Then you can buy the special edition with both tomes in a cool slipcase and neat maps!
