Malignusak

Malignusak is a term used in popular fiction and fantasy folklore to describe a malevolent force or substance whose influence is deleterious to living beings and objects. The word is not tied to a single canonical source, and its meaning varies by author and medium. The etymology is opaque; most uses treat malignusak as a neologism derived from the roots malign- and a suffix -sak, with connotations of corruption or contagion.

In narrative usage, malignusak is described as persistent, capable of lingering after exposure, and often spreading through contact or proximity. It may inhabit artifacts, locales, or beings, and tends to undermine agency, memory, or vitality. Manifestations range from shimmering residues to intangible pressure or a chilling sensation. Some works portray it as a sentient or semi-sentient force that resists purification.

In tabletop RPGs and video games, malignusak is frequently used as a curse factor or corruption mechanic, requiring cleansing rituals, purification quests, or protective wards. It may be quantified by risk tokens, corruption meters, or sanity checks.

Because it is a fictional concept, there is no single authoritative definition; readers should consult the specific work or setting for details.
