[akhtene]

It is said that Orcs had no language of their own, but took what they could of other tongues. Hence there was no 'orkish' letters.
The Black Speech devised by Sauron hardly had its written form (Who would need it? Orks or trolls?)

Thus what is left for Sauron to engrave his verse? Only two alphabets, and both of elven origin. So Tengwar was probably chosen as more ancient and finer looking (in both senses)

Now for Legolas's comment: Can an Eye write? or print? or engrave? or...
It definitely means Sauron DOESN'T use ANY runes at the time. [img]smilies/smile.gif[/img]
