Talk:Rubedo/@comment-4905541-20150813111947

Hmm, according to wiki, alchemy's Magnum Opus has four stages which got shortened to three. Interestingly, it goes as follows: Nigredo(Black) > Albedo(White) > Citrinitas(Yellow) > Rubedo(Red/Purple). When the four stages were shortened, Citrinitas and Rubedo were combined (apparently because the color Yellow is related to the color Red thus leading to the belief they belong to just one stage in transition).

If you think about it, the theory about Rubedo being two beings/personalities might actually be possible seeing as if there were only three sisters in the Nazarick NPCs, Rubedo would have to represent both Citrinitas and Rubedo stages. Someone also mentioned Rubedo is possibly the "double golems" on the 8th floor which could also support the theory seeing as Ainz mentioned "operation test".

Strangely enough, it's believed that the four/three stages of the Magnum Opus is what leads to the creation of the Philosopher's Stone. This might hint on the possibility that Nigredo, Albedo, and Rubedo working together or being used in some sort of event/ritual would create one. Whether this idea will be included in the novels' story later on is subject to the author's will.

Personally, I think the author can make the three sisters have the ability to make a Philosopher's Stone which could then be used by Ainz to make himself the ultimate being and maybe have a flesh and blood body again, with overwhelming power. The stone is often hailed as the ultimate goal of alchemy which is also often considered to be the "elixir of life". If the Necronomicon could make Ainz into a Lich, the Elixir of Life could make him back into a living immortal being. IMO anything goes in the New World.
