how did you work that one out Kat?
Slowly being driven insane by work
-or-
I just don't want him to be one of the shiny gold figure that stood on the Bluestar's left side
-or-
1) He is one of those watching from on high, helping as able from there as well. Long ago Oberon was able to come back as a messenger of sorts. Quarion could be sent back for the same purpose. The last paragraph also leads to Quarion possibly, someone sent by the light, sent to us specifically- a messenger.
2) We are close to Quarion's Rest yet it is unlikely that he is actually buried there. He was close to Link it is possible the woodshadow got him and/or his family to agree to have him buried some place safe as all the other hero's were. A place not easily thought of nor easy to find. Hywrl is Link's area a place he could watch over the grave, a quite honor place of rest. Link was the last and if Quarion made it to old age there was only Link to make sure he got there, and with Link he may have gotten stopped along the way and come up with his own idea and gone with it.
It is very likely by the story of Quarion that the two found each other alive later on. That woudl explain the switch in Quarion from 'Find Link!' to 'He's dead stop looking.'
3) It was someone who had been alive previously but does not hold thier memories. Someone who once held power, but now does not (comment about not its time). Someone close to dwarves and thier love of iron work (comment about fiting tribute and not much changing). Someone from the old world as he calls it 'Thane's religion' not the light or Apectos, but Thane. Someone who knew him, worried about the teachings he spread as he was glad things did not evolve into seeing Thane as a god.
4) Could be a dwarf since it references walking among them and part of thier speech or som such not being lost.... but could also just be Quarion who in building the wall spent years surrounded by dwarves in thier own element.
5) The sword is that Quarion was a sword man, ::shrug:: I don't know.... fits, and explains a possible place of how Jaine got it. She didn't craft it herself. Also the person did not know it exactly, and since it changed from (whatever it's name was before) to loss that could cause the familiar feeling of the sword to its owner.
He was more of a short sword guy apparently, but the sword does keep changing as it is magical.
5) The part about the queen looking like one of mine though does first lead to Oberon, but in all those years there could have been mixing of blood. Not really far fetched since his would have been an honored house and his ancestors would have pull and power. Something leaders and other powerfully people would want to ally themselves with.
Plus Quarion himself was related in, as he was most likely related to the amastatia who was one of Oberon's many decendent children.
6) Also there is the whole you can only be brought back once- Oberon died long ago was brought back by the hero's of old; Link died was brought back- Still available to Quarion though.
I know and already said this is tenuous reasoning and obviously a mass of other people could it be instead. Just a random mind wandering that I came up with

I think Gertie was more correct with Oberon and see more connections that way from the messenger of the light wording 'to one of his' to any number of other things.
