Feanor's presence in Cirith Ungol

[Aiwendil]

Manwe Sulimo:

Wait...but is it in the Tengwar? I don't claim to be a linguist, but I thought that the Tengwar was the written style in the appendices. Unless you meant Fëanorian script. Although I'm not sure what the inscription on the One was written in....

Earwen:

In the book it says its the balck speech of Mordor. So how can it be Tengwar?

The Feanorian script is Tengwar. It was invented by Feanor in Aman and superceded the alphabet of Rumil (which might also be called tengwar (literally "letters")).

The Ring inscription was indeed in the Black Speech, but it was spelled in Tengwar, just as English, Spanish, German, and many other languages are all spelled with the Phoenician alphabet.

Davem:

And isn't there a link between the Trees & Shelob, as last child of Ungoliant who slew the trees.

I definitely think so. Also, recall that Ungoliant desired to consume the Silmarils but that Melkor wouldn't allow her to.
