Well to answer your question no I haven't gone through these concepts since I am not really aware of the mythology behind them, although I did quote in my article
The Morning of the Magicians by Jacques Bergier and Louis Pauwels, in which they suggested that a secret Vril Society existed in Weimar Berlin. I believe that this supposedly "superior subterranean master race" can be tied to the Dark Men the group of broken ones living in Lekar, making their homes in the Lekar Sewer System (it suits the tradition of Ravenloft's pervasive adaptation of historic or fictional characters, places etc).
The "all-permeating fluid" called "Vril", a source of energy that the spiritually elevated Vril-Ya from
The Coming Race novel are able to master through training of their will was in some ways covered by the Psychic Lost One form QtR#28, where Vjorn Horstman tries to find alchemical ways to unlock the powers of the mind (or perhaps make ordinary people able to control this "all-permeating fluid").
As for drugs and warfare it is not just in WWII that they have used drugs, although Pervitin (meth) was used extensively by the Nazis other armies used drugs too, methamphetamine was also used by the Japanese while British and American forces used amphetamines (which became part of the US med kit). Tobacco was extensively used in WWI. Alcohol also called "liquid courage" was used before that as in the Russo-Japanese war where the czar built up his army with vodka revenue. Drinking and war-making have gone hand in hand since antiquity, and in the Middle Ages battlefields were drenched in beer and wine.
The Scythians burned stacks of cannabis and inhaled the smoke and others had used this drug before them in rituals, although it is not proved if the Scythians used it before battle, it is a theory. While the formidable
Order of Assassins (Persian: حَشّاشین, romanized: Ḥaššāšīn) name has its roots in hashshāshīn ("hashish smokers or users"), it was used figuratively, the term hashishi connoted meanings such as outcasts or rabble, was first used by Fatimid caliph al-Amir bi-Ahkami’l-Lah, without actually accusing the group of using the hashish drug, the caliph used the term in a pejorative manner.
From 1898 through to 1910, diamorphine was marketed under the trademark name
Heroin based on the German heroisch which means "heroic, strong" (from the ancient Greek word "heros, ήρως" meaning hero) as a non-addictive morphine substitute and cough suppressant (hm...that worked well

).
Drugs and war have been intertwined since forever so it couldn't be missed from war-mongering Falkovnia.
