These flying humanoids are distantly related to kobolds.
     Urds stand three feet tall and have‑ short ivory horns, red rimmed eyes, and flattened noses. Their bodies are thin, frail and covered with mottled yellow to brick‑red scales. Leathery, batlike wings sprout from their backs. When flying, these wings stretch eight feet or more across. On the ground, urds move with an awkward half‑walk, half‑hop gait. 
Urds speak their own language, as well as Draconic, and a smattering of common.

Combat
Urds hunt in great flocks at night, using their darkvsion to spot prey on the ground below. Urds attack by dropping stones upon their victims. These "rock bombs" weigh two to three pounds apiece and are covered with jagged edges and protrusions. Unsuspecting victims are treated as AC 10 for the attack roll. Each rock that hits causes 2d4 points of damage. About 75% of the urds encountered carry one rock bomb apiece. The remaining 25% carry half spears, which can be used either as spears or as javelins. 
     Light Sensitivity (Ex): Urds suffer a -1 penalty to attack rolls in bright sunlight or within the radius of a daylight spell.
     Skills:  Urds receive a +2 racial bonus to Move Silently and Spot checks.

Urd Shamans
Urd shamans are adepts of 4h-8th level, that also have the ability to speak with bats as per the spell speak with animals.
