OlcEdit

Could you clarify what "Olc" refers to in this request? It could be a real-world organization, a historical figure, a concept, or perhaps a fictional or hypothetical topic. Once I know which sense you intend (or if you’d like me to treat Olc as a broad, multi-meaning term and cover the most prominent interpretations from a conservative perspective), I’ll write the encyclopedia article in the requested style with the required formatting and see-also links.
