The most concerning of all the recently discovered types of Phrax, Void Phrax is an outlier in which unlike others growing in abundance in a natural environment - Void Phrax only grows in the darkness of impact points from the Night of Falling Stars. Within these zones other types of Phrax can grow just as sporadically. Whilst one minor would call it good fortune, a veteran would call it a warning sign. Just like how unrefined Phrax Crystals can be volatile, if a good enough impact hits THEM then Void Phrax is far worse as effects coming from striking one of these raw ores can vary astronomically. Whilst Scorch Phraxcrystal can result in an explosion, and Spark Phraxcrystal can have lightning shooting down the mine shaft, Void Phrax has terrifying abilities to release gasses that can send droves of people insane or warp the very stone around to create impromptu life which shouldn't exist. The result of a few too many mining operations has made the discovery of Void Phrax within a mine a quarantine-level event. Worse than this are those that illegally smuggled Void Phrax to whatever deranged Wizard, Artificer, or noble with a god complex who think they can harvest this 'true power' of the void.

In today's age within mostly cities and the most traversed towns, Phrax Items have become more commonplace to elevate the living standards of the common wealth. These days, frost & scorch Phrax have been utilized either in combination or separately for various household amenities such as indoor plumbing, heating, and some storage capabilities for food. Spark Phraxcrystal has been most dominant for lighting fixtures in addition to Artificers & Wizards for rudimentary electronics. Unbeknownst to most, Quartz Phraxcrystal has been used to fortify many of the most significant establishments, monuments, and fixtures within cities. It has become more commonplace to embed Quartz Phraxcrystal in the outer walls of outposts, mansions, and of course for royalty. The harvesting & distribution of these phrax are handled by the governments of many nations to ensure proper export & import. Also as well to keep the usage of Phrax in control per their standards. This has created a wealth gap for many smaller towns & villages as there has been troubling implications amongst merchants of many creates of Phrax going missing due to an alarmingly rising new threat of the Aura Eater, or by the hand of man in which these crystals may easily become a powerful destabilizing weapon.
Depleted phrax crystals that haven't been sacrificed for spells can be recharged either by environmental exposure or by supplying mana directly to it. These recharged phrax crystals have a non elemental property and don't explode when shattered.
