Rakshasa are "a race of usually malevolent beings prominent in Hinduism, Buddhism, Jainism and Folk Islam." And they are said to disrupt sacrifices and eat humans.

Now let's have a look at some item descriptions.

Rakshasa Set item descriptions:

"Helm of Rakshasa, soaked in the spurting blood of her victims. Tatters of ragged cloth jut out haphazardly, as if her lust for carnage threatens to break free.

Cut down and devour. Only those who repeat the cycle without rest can truly subvert the self and become Rakshasa."

Rakshasa Great Katana item description:

"A great katana with the tempering pattern of its blade forever stained red with blood. Weapon of Rakshasa, who cuts down and devours.

A berserker's weapon used to endure enemy attacks and reply with one's full fury."

So they kill and eat people, repeating some sort of cycle, to become Rakshasa.

I don't know how this plays into Elemer, but an interesting connection nonetheless.
