Now ... point could be tip/period (full stop) /even a point of an argument/purpose, rather than a compass point.
Trinket could be toy.
Trouble is, the nearest thing to a ring is a bangle or bracelet ... tried both. And chain.
I tried to get from bangle to Aglareb ... is that even a place, though?
I have the feeling it's one of the Third or Second Age ones, because everything is part of the story/timeline in the First Age ... Fords of Isen or Gladden Fields would be favourite if they had a T, or Last Alliance if it had a trinket.
(Actually, we need it to be a river that was fought over ... Gladden means yellow iris, I think, so no stream element in that or Last Alliance).
