Kolmiessa

Could you clarify what you mean by "kolmiessa"? It could refer to different things, and I want to avoid presenting incorrect information. For example:

- a Finnish linguistic term (possibly the inessive form of a word related to three or a triangle, such as “kolmiessa” meaning “in the triangle”)

- a real place, organization, or project with the name Kolmiessa

- a fictional or hypothetical concept for a wiki-style entry

If you specify which interpretation you want (and any factual details if it’s real, or that it’s fictional), I’ll write a concise, neutral wiki-style article under 300 words.
