The book of magic

After the initial shock, a tough negotiation followed, and finally the players came to an agreement according to which the Vertrans would provide food to the players for a period of six months, as well as basic equipment that did not involve giving them the magical technology that the Vertrans had built during their stay in Athair. They had spent millennia to get to this point and they would not give it to them for all the crystals in the world, the agreement would only include common objects and other more basic belongings such as clothing, footwear and items that were useful for the construction of the settlement.

Money opened borders, as they said on earth.
