[Gothmog]

I can only apologize! To my defence I must tell you that I didn't see Morsuls last post about the lighthouse (well, it wasn't a lighthouse but probably looked something like one), but still this was mostly thanks to you I guessed it right. But I realized early that "ancient eye" must be a palantir. It was those "three" that confused me... However, here's a new chance for you Morsul. Quite easy I think, and not to well composed I'm afraid. But this is the only thing I could come up with right now:

One of brothers three
A king one can't see
The jewel his doom
Killed in his own room

Good luck! And I hope you can forgive me, Morsul
