Although it is one of Azathoth's servants, Kaajh'Kaalbh is rarely seen on our plane of existence as it is sequestered in a dimension of pure chaos. As a result, it has no "true" physical form, it's body being constantly torn apart and reformed in new and bizarre ways.
The only time that Kaajh'Kaalbh will be encountered in this dimension is on the occasions that it is summoned by a practitioner of dark magic, and this act requires the assistance of one of the hostile aliens known as Dimensional Shamblers. Even so, the form that Kaajh'Kaalbh manifests during these summonings is completely unpredictable; it is as likely to appear as a great lake of cooled quicksilver as something recognisably sentient.
- Kaajh'Kaalbh made its only appearance in Philip José Farmer's short story The Freshman (1998).
