Conversion Monster : Arch-Shadow / Demi-Shade

[Nahal]

Hi. I am looking for a 3.5 converted version of the monster (or maybe a template) called Arch-Shadow or Demi-Shade. It appears in the Randal Morn adventures (Dales Trilogy). Could anyone help me or give some suggestions ?

Thanks for all.

As far as I can tell it's never been updated to 3.5e. It appears in Monstrous Compendium Annual 2 as well. I can't find it on Creature Catalogue either (one of ENWorld's Hosted sites).
