Thanks. So, I think I have found a name for this ability: Aura of Oblivion.
It can be generated by either an artifact (a major psionic artifact, I call it the Shard of Oblivion) or manifested as a personal power of an epic psion.
This aura also works on any non-living entity that contains information, so it would affect undeads (corporeal and incorporeal), spirits, constructs such as golems, spells and psionic powers that store information and so on.
I'm thinking that this aura should be available only for a level 40+ psion, is that reasonable?
