Yliittimet

Could you specify what Yliittimet refers to? Is it a real place, a historical or cultural term, a scientific concept, a group or organization, or a fictional concept? Also, do you want the article in a Finnish context or a general international context, and should I treat it as real or fictional? If you’d like, I can proceed with a concise, neutral wiki-style entry under 300 words once you confirm the domain and nature.
