Mark of Shadow: UA v. WtGE

[LibraryOgre]

Are there any significant differences between the two? I have the UA, but don't want to get WtGE for a single variant.

(Note: I don't need a rundown of the differences... just "Are they big enough that I have to buy it")

As far as I can tell, the two are identical, including the Greater Dragonmark feat.

Excellent. A player requested it, and I'm planning on including it into the Realms as "weird variant race due to sorcerous background."
