saliache elves are ayleids.

and the full text is
One does not need a background in Ayleid history to identify the origins of these facial markings, but only those with a vast knowledge of the Saliache Elves will truly appreciate the meaning of their design

those with vast knowledge of the elves will appreciate the design, not the elves.
and it looks just like the design of ayleid gates
