The Widow Harun
Teylas is the Tuigan name for Akadi, the sky-god. Actually the elemental lord of air, Akadi is one of only two Faerunian gods traditionally worshipped by the Tuigan, the other being the elemental lord of earth, Grumbar, known as Etugen.
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.
