Grograman is the guardian of Goab, the Desert of of Colors, which exists in a state of symbiosis with Perilin the Night Forest, turning into an obsidian statue at night in order to allow Perilin to grow.
Grograman is known as “The Many Colored Death” because he both has the ability to change color depending on the sand he is standing upon and everything, even the most powerful creatures, are reduced to ashes in his presence.
Grogroman is said to "bring the desert with him" because he burns everything around him into sand. Bastian, who is made immune to this effect by the power of the AURYN, is the first being living to befriend him, so Grograman gives him the magical sword Sikanda.
Grograman is like a huge lion that changes colors like a chameleon based in the color of the sand he is walking on.
