Portals, a form of advanced magic capable of creating rifts in the fabric of space-time, are considered one of the most dangerous and unstable types of magic in the Arcanex Galaxy. Despite their potential for instantaneous travel between distant locations, the inherent instability of portal magic often leads to catastrophic consequences.

Portal magic is extremely unstable and more often than not results in massive explosions that devastate worlds and surrounding areas. The process of opening a portal involves manipulating immense amounts of arcane energy, which most of the time leads to a catastrophic release of arcane energy. These explosions, known as Arcane Detonations, have the power to obliterate entire regions, causing widespread destruction and loss of life.

One of the most infamous incidents involving portal magic occurred between the Volkyrans and Humans. The Volkyrans, naturally attuned to magic, were the first to master portal magic and used it to unintentionally travel to the human homeworld. While initially beneficial, the collaboration between the Volkyrans and Humans to open a return portal resulted in a devastating explosion. The portals on both the human and Volkyran homeworlds exploded with such force that it wiped out life on nearly one-third of each planet, leaving vast areas uninhabitable.

Following the incident, the Volkyrans decided to conceal the secrets of portal magic. Recognizing the extreme danger it posed, portal magic was quickly outlawed in both human and Volkyran territories. Early mages who experimented with portal magic inadvertently caused a series of devastating explosions, which only reinforced the decision to ban its practice.

Through these mishaps and the gradual spread of information, the inhabitants of the Arcanex Galaxy came to understand that portals were not a reliable method of travel but rather a perilous and disastrous magic. The risks associated with portals included not only the death of the casters but also the destruction of the surrounding area and the location where the other end of the portal opened.

In modern Arcanex, portals are universally avoided. The catastrophic history associated with portal magic has left a lasting impact on the galaxy's inhabitants. Despite the theoretical potential for instantaneous travel, the practical risks make portals an unacceptable and forbidden practice. Scholars and mages study portals only from a historical perspective, with strict regulations ensuring that no one attempts to reopen these dangerous rifts.

Portals remain a subject of fear and caution, a reminder of the volatile power of arcane magic and the importance of respecting its boundaries. The lessons learned from past tragedies continue to shape the practices and laws surrounding magic in the Arcanex Galaxy, ensuring the safety and stability of its diverse civilizations.
