The NewHorizon (called in short NH) is a transportation service organized by a nation (Fyros, Zoraï, Tryker or Matis). In each city (Pyr, Yrkanis, Fairhaven and Zora, but also Min-Cho, Thesos, Avendale, Davae, etc.) a NPC carrier, named "New Horizons", allows you to travel to another city located in the same country.
Such a trip costs you 3,000 dappers unless your fame with the corresponding nation is maximum (100), in which case the trip is free.
It is to these NPC Transporters that you can offer the products of the basic Occupation (Occupation mats).
