I [...] couldn't rule it out completely since Liminalities are inherently unpredictable and the field is young, but nothing like that has ever been recorded. There are cases of individuals with pheromone manipulation, usually involuntarily, but I don't think it could specifically effect only non-liminals. Liminals are still human, so human pheromones should impact all humans.

Again, why? I don't doubt your scientific curiosity but this is very specific.
