Siela is the name given to the religion practiced by the Meó. It is based off the Five Deities. Five is an incredibly sacred number to the Meó. The Siela religion is deeply embedded within Meó culture to the point that the line between Siela and Meó culture is often incredibly blurred. The five deities are as follows;

Amáko - Deity of the Mako, the Terrestrial Living, the Ground. Element is Wood. Associated tribe is the Malo.

Akiá - Deity of the Wheel, the Flying Living, the Sky. Element is Metal. Associated tribe is the Sati.

Ahké - Deity of Haki, the Haki/Mystical Living, Haki. Element is Life (Sie). Associated Tribe is the Varisti.

Amiru - Deity of Miru River, The Aquatic Living, the Void. Element is Water. Associated tribe is the Kuana.

Áhko - Deity of Ahko Tree, the Sapient Living, the Sun and Stars. Element is Fire. (Note that Áhko's element is not wood as the Ahko Tree is not in fact a true tree, and is much more like a grass, and does not produce wood.) Associated tribe is the Salinke.

The five deities are a core tenet of Meó society, and at birth every child is assigned one of the five deities. People are addressed by varying forms of honorifics based on their deity. Although all deities have an associated tribe, this does not necessarily mean that an individual of a tribe must have their associated deity, quite the opposite in fact, with every tribe having a decent portion of each of the deities. Some Meó may choose to contact an adviser when assigning a deity, although this is coming increasingly less common in the modern Meó society.

In relation to immigrants or assimilated people, it is common practice to be assigned one of the five deities by a spiritual leader.
