That shouldn't really have anything to do with the artifacts. Let me give you some background lore on why the Zone exists.
After the Chernobyl NPP melted down and the exclusion zone was set up, scientists set up secret labs in the Zone to do secret research.
Part of this research is the C-Consciousness project, which attempted to fix humanity's flaws (eliminating greed, cruelty, anger, etc) by attempting to alter the noosphere (an invisible field affected by and affecting human cognition).
They did an experiment to attempt to alter the noosphere which backfired horribly and ended up damaging it, and that is what resulted in the creation of the Zone and the anomalies within it.
Even after C-Con is destroyed due to Strelok's actions in SoC the Zone remains as the damage to the noosphere appears to be permanent.
The Wish Granter is not directly related to the anomalous phenomena inside the Zone, it's a trap built by C-Con to deal with intruders.
