The Widow Harun
Etugen is the Tuigan name for Grumbar, the earth-god. Actually the elemental lord of earth, Grumbar is one of only two Faerunian gods traditionally worshipped by the Tuigan, the other being the elemental lord of air, Akadi, known as Teylas.
Akadi and Grumbar are discussed in more detail in Faiths and Pantheons and other Forgotten Realms products and supplements. Please consult these to learn more.
