An Ukkula is a strange creature from Beyond the Outer gates and as such is classified as an Outsider. The creature possesses a long insect-like body with narrow whip-like tentacles instead of legs. At it’s front is a massive eye ball, which is capable of 360-degree rotation.
Ukkula are capable of seeing through solid objects. They can see in ultraviolet, x-ray, and infrared. It is known that they are capable of seeing invisible creatures, as well as seeing auras, and seeing through glamors. It is because of this ability, in fact, that they are often employed in the capacity as sentries.
Ukkula are capable of raising a telepathic alarm, and so sometimes act as a form of silent alarm system as well.
