We discussed this previously when Chaos Tunnels scans were removed and decided to keep their information on a historical subpage. Since White Wolf Mountain and some outlying desert and Khazari Jungle scans have now been removed as well I think that this needs to be reviewed again (in the meantime I moved White Wolf Mountain scans to the former locations page and the outlying images are sitting in Special:Unusedimages).
The main argument for keeping historical information last time was that Chaos Tunnels scans remained in game for people who had already obtained them. This is not the case for White Wolf Mountain scans; as stated in the update post/patch notes the scans were completely removed and replaced by Menaphos scans. Given some time has now passed we can also assume that very few, if any, Chaos Tunnels scans still exist also. Therefore I do not think it is necessary to keep the full information about all possible clue locations; the images will increasingly bear no relation to maps/ingame graphics as the game is updated and will be of little interest to readers. A mention of particular locations being removed and when they were removed in the main page's trivia section is sufficient.

Delete - Per Isobel, if it comes to light that they carry enough historical significance we can host it in the userspace. But it seems kinda of silly to keep information on something that no longer exists ingame and will not make a reappearance. 16:32, March 6, 2018 (UTC) Delete - Same as Zafryna said. No point keeping an article that doesn't (currently) have any historical value 15:03, March 21, 2018 (UTC)
