Provenance
Where it comes from.
Here's the honest version: Remeca is a made name, a NameTale coinage with no dictionary root to trace. We shaped it for sound rather than descent, letting three soft syllables carry the weight a meaning usually would.
If it seems to lean faintly Latin, that is a family resemblance and not a lineage; the open vowels and the '-eca' ending simply ring like plenty of real words without borrowing from any one of them. Treat the blank slate as the gift: no old baggage to explain away, just a clean, sayable shape waiting for the story its owner decides to give it.
