'''Note1''': There is also world called ''Gehenna '''Prime''''' detailed in an article with the title ''"Storm over Gehenna"'' published (amongst other formats) in [[Fanatic Magazine|Fanatic Magazine #03]] and also online as a pdf-file. As the ''Fanatic Magazine'' regularly included articles submitted by hobbyists that may be in contradiction to established background (as is the case here) the information contained in these sources always takes a backseat when compared to official, "proper" publications. For information on this "second" ''Gehenna Prime'' that probably has nothing to do with the "real" ''Gehenna Prime'' jump to the section entitled "Gehenna Prime (Specialist Games version)".'' '''Note 2''': ''Attention should be paid to the fact that the so-called [[Gehenna Campaign]] of 955.[[M41]]{{Fn|5}} took place on a planet called ''[[Gehenna]]'' (and '''not''' ''Gehenna '''Prime''''' which this article is about) which featured the "dusty wastes of Gehenna" (again no such such mention for Gehenna Prime), therefore it is entirely possible that these are two different places altogether. In addition official sources also mention a [[Forge World]] called ''Gehenna''{{Fn|6a}}^,{{Fn|6b}} which might or might again not be the place where the aforementioned ''Gehenna Campaign'' took place but certainly does not seem to be identical with ''Gehenna '''Prime''''' as the latter is no Forge World.

'''Note3''': ''No dates are given for either [[Waaagh! Hargluk]] nor the [[Genestealer]] infestation uncovered by [[Inquisitor]] [[Kruger (Inquisitor)|Kruger]]. [[Codex: Space Wolves (2nd Edition)]], pg. 47 established that the [[Great Hunt|Ninth Great Hunt]] "led to the destruction of the Genestealer infested worlds of the [[Gehenna systems]]" but did not specify a year for this event. [[Codex: Space Wolves (7th Edition)]] (Wulfen edition) sets the ''Ninth Great Hunt'' in the year 671.[[M34]].{{Fn|7b}} Not to mention that [[Games Workshop]] not only used both the plural ("Gehenna system'''s'''{{Fn|3}}) and the singular ("Gehenna syste'''m'''{{Fn|7a}}) but that (see the note Note 2 at the very top of the article) it could also be possible that the Space Wolves' action did not even take place in the "Gehenna system" which ''Gehenna Prime'' belongs to but in the putative Gehenna system where the [[Blood Angels]] campaign took place. The latter theory does not seem too far-fetched when one considers that there certainly was a [[Tyranid]] splinter fleet which attacked the ''Gehenna'' where the Blood Angels were fighting the [[Necrons]]{{Fn|5}}; and where there are Tyranids, Genestealer infestations are often not far. In addition the main source for the history of ''Gehenna '''Prime''''' does not mention any other inhabited worlds among the 17 planetoids of the corresponding "Gehenna system"{{Fn|4}} whereas the Space Wolves are supposed to have destroyed multiple Genestealer infested worlds.{{Fn|3}}^,{{Fn|7a}} There does not not seem to be a definitive answer to this conundrum of which Gehenna is which and in which system, as it is quite possible that it is just another one of those cases where ''Games Workshop'' simply used the same names for different places and persons for unknown reasons. The sources being as they are and there not being a mention of ''Gehenna '''Prime''''' in the sources mentioning the Space Wolves this event for the time being (i.e. until another source is more specific) will not be included here.''

'''Note 14''': ''From the information available about the Genestealer infestation{{Fn|1}} it could be assumed that the [[Imperium]] in the end managed to defeat the [[Orks]], as in [[Warhammer 40,000: Wargear (2nd Edition)]] on pg. 60 it is written that: "[...] The [[Space Marine]] [[Chapter]] [the [[Blood Angels]]] was almost worshipped here [on Gehenna Prime] since the time they had helped drive off the Ork invasion". Of course there is also a theoretical possibility that this refers to an so far unknown Ork invasion other than [[Waaagh! Hargluk]].''

'''Note 25''': ''Taking into account the previous note 1 Note 4 (see above) this [[Genestealer]] infestation could have happened after the [[Ork]] invasion of Gehenna Prime by [[Waaagh! Hargluk]]. This is however only an interpretation of circumstantial evidence as it is not explicitly stated when which events took place. As to the [[Space Wolves]]' "destruction of the Genestealer infested world of the Gehenna systems"{{Fn|3}} please see the note Note 2 at the beginning of the section "History".''
