Lu-Kthu

Lu-Kthu is an Outer God from the expanded Cthulhu-mythos.

Overview
Lu-Kthu is said to be the Birth-womb for the Great Old Ones, similiar to Shub-Niggurath.

It is desricbed as a planet-sized mass of entrails and internal organs from the distance. On a closer exmanation it looks like a ''wet, warty globe, covered with countless ovoid pustules and spider-webbed with a network of long, narrow tunnels. Each pustule bears the larva of a Great Old One''.
