Finduilas II and her entire dysfunctional family belong to J.R.R. Tolkien.
Faramir once dreamt of his mother being swept out to sea; but then, he never knew his mother.
In truth it was a slow and silent wearing. A shoreline inside her like a cut, a new grain rubbed loose every day, so that the same Finduilas never woke twice. None of the men who loved her knew her, not even the ones old enough to remember.
To be the victim of a greedy tide would have been a kinder fate.
