[Urwen]

Alas, my little trick is uncovered.

Telperien: She is endlessly full in reverse, with German one spinning.
??E??: The largest Australian lizard goes in circles and gains direction.
??L??: Turn a class of vertebrates around. Shorten England.
??P??: A compound and an element spin together, chemically speaking
??E??: Deceive, according to number. It's all jumbled up.
??R??: A scheme changes vowels and a wheel cover gains one, in a muddle
??I??: A hormone and a lake without eye. It's all broken.
??E??: Elite skill in a daze.
??N??: A Tree changes a vowel.

I knew you would get it almost immediately. This has been Urwen's revenge.
