durades

Could you specify what sense of "durades" you want the article to cover? For example:

- a real-world term in geology, linguistics, archaeology, biology, etc.

- a surname or cultural reference

- a fictional or creative concept (and if so, any setting or domain you’d like)

If you prefer, I can also draft a concise encyclopedia-style article assuming a fictional concept. Let me know which direction and the desired length (default around 150–250 words).
