I now know that the central figure depicted in the tapestry above Monohan's hearth is Alastar. The star too far still watches over Tanglewood, and I think Colin in particular. I wonder if there is some undiscovered relation there that the trees have not yet revealed to me. Perhaps even the trees do not know themselves.
But there is the mystery of Colin's fey blood to consider. And Bairtlemead has his own suspicions as well. I can only hope that all will be revealed in another tale.
