Sara Oakheart is a mysterious old lady who once lived in a cottage on the river in the Trollshaws. Questions are raised whether her Rotted Diary might be found within the charred remains of the Crumbled Cellar where she lived.
Recently the mythical Sara has been seen in locations (instances) at the most curious locations all over the Middle-earth. She repeatedly gets herself into trouble and put heroes at risk saving her neck, as if on purpose. She hobbles very slowly, then suddenly speeds up and runs into trouble once again. She has been seen at:
Indeed a traveller that shuns no distances, what does she hide under her wrinkled skin? (See spoiler below.)

Contents of Sara Oakheart's Rotted Diary
- (The cover of this journal has given in to rot, but you can just make out the notation 'S. Oakheart.' The first twenty pages are damaged by the damp and are illegible, but you can just make out some writing in a crabby hand halfway down one of the discolored pages.)
- ....weather today was grey and cloudy, giving way to rain in the afternoon. Brought two chickens to share with L, but his spirits were low, and I think the food brought him no joy. Understandable, of course, Keeping N within the walls of Sithad must be a great sorrow to him.
- (The next several pages are illegible, and some leaves are torn and missing.)
- L told me today of my predecessors -- the long lives of Elves are a wonder to me, and he spoke with distressing honesty of his reason for choosing N's keepers from among my kind, and not of the Eldar. His own people would disapprove, but more than that, he desired no one caretaker to be so near to N for so long. The short lives of Men better-suited his purposes. I thought this rude, but he did not seem to notice. Oh, Sara -- you are old enough to know not to take it amiss! You have not heard it all, certainly, but by helping....
- (The next page is missing, and when the text resumes, the ink is smudged and the hand messier than before; it's writer was apparently in a hurry.)
- ... is missing, and L fears the worst. I will carry out his wishes by breaking the keys to Sithad (the stones of Tâl Bruinen are heavy and will serve) and hiding them. I will not tell the Elf where they lie, but I record it here if there be need. To hide it, from the eyes of....

- ... must stand at the stairs of Sithad, looking up towards the enterace. Turn to the left and walk forward to the wall, and then turn right and follow the curve until you see four pillars through two pillars. Walk between the two and look to the right of the four. I will leave the keys always in the shade.
- L fears for me, but I will be fine. I am not called Oakheart for naught, and he tells me I guarded N for longer than any other. I have nothing to fear.
- (The rest of the diary is blank.)
Candelleth in Echad Candelleth explains more about her diary:
- 'What is this, <name>? A journal? Can it be? I do not understand. Amarthiel cannot have...there must be more to this riddle than we know, <name>, for I am filled with confusion. But hearken to this:
- "...brought two chickens to share with L, but his spirits were low, and I think the food brought him no joy. Understandable, of course, Keeping N within the walls of Sithad must be a great sorrow to him."
- 'Whoever Sara Oakheart may have been, Amarthiel in disguise or not, it is plain to me of whom she speaks: can "L" be any other than Laerdan, or "N" anything but Narchuil? We are close, I can feel it. The secret lies within this journal, friend <race>: the diary of Sara Oakheart.'
From Book 9 she is later revealed as Amarthiel, champion of Angmar. Amarthiel slew Sara Oakheart and took her form, pretending to be her own jailer to sow confusion among the Free Peoples.
