The Initiation Campaign starts here.
It was during their travels that the Travelers met locals who had observed strange phenomena. Bright, shimmering spaces showing a landscape of another world. Going around it was easy, but crossing it meant a journey of no return because the Portal disappeared immediately, leaving behind many gems. The news spread, and the gem appearance zones were analyzed and mined to recover all the wealth of the places.
These entropic phenomena were studied by the local scholars, and the cursed success was achieved in some worlds that knew how to unite the science with the magic of the Nexies. The alliance of these two empirical knowledges, one logical and the other chaotic, allowed the scholars to discover how to make a portal appear linking their world to another. The powerful immediately saw infinite possibilities: expansion, rapid gain of resources sometimes non-existent in their world, exile to a new world safe from harm. Thus, the leaders asked the scholars two things: to make the technique reliable and to be able to choose the world of destination. This is how the observers saw the wars of power extend not only in the worlds but also between the worlds.
