One of the things I have tried to do with Kílta, though it is a personal language intended for use in the here-and-now, is to assemble an invented legendarium I can use to expand the range of expression beyond the nakedly literal. Stones, for example, are associated with a (completely undefined) oracle system, allowing the creation of idioms like ëkin mika si autto she touched another stone, to refer to someone altering their fate in a notable way.
Within this legendarium are váchur, semi-personified representations of certain forces and entities in the world, not gods, but certainly beyond the human. Perhaps like genius loci but expanded beyond just locations.
Kílta already has a word for plague, epidemic: vós [ˈβoːs]. But it entered my mind that a vácha for that might be useful. After a bit of percolation my brain, the vácha Hësas [ˈxə.sas] has entered the legendarium. It is represented by flies, who in Kílta already have associations with the more remorselessly brutal parts of the natural lifecycle.
In Kílta, many things that move in the air tunáko hang there. Because Hësas is represented by flies, I have decided that when expressions of location are used with the plain old word vós epidemic tunáko will be used.
Vós në méka nen metúnakësto.
vós në méka nen me-túnak-ëst-o

The plague is now in America.
Normally using a posture verb for location is confined to people and animals, but I've extended it to vós because of the association with Hësas and flies. This is probably the most subtle result of using the legendarium to drive Kílta expression to date — a single usage note in the lexicon entry for vós.
