Skreek (2008)

From Introduction:

Completely loyal to the Raiders Guild, these masterful scouts make their home within Guild strong holds, mimicking their lost caves within.
Beware any who cross a skreek for hiding from them is near impossible.
Play a skreet if you want...

• to be silent and eerie.
• to daze your foes so that others may move in to attack.
• to be able to climb easily and hang upside down.
• to be a member of a race that favours the rogue and ranger classes.

Physical Qualities
The skreek are short, hunched, bat-like humanoids. Their exaggerated frames sport broad upper torsos, narrow hips, and oversized feet. Their fur ranges in color from light gray to chestnut brown to nightblack. The clawed hands of a skreek are surprisingly dexterous. They move with a quiet, creepy grace and, when not in motion, achieve a preternatural stillness. Skreek ancestors lost their wings long before the race achieved sentience; a vestigial remnant appears in the form of a pronounced underarm membrane.
