Hi I suggest some items from the peruvian culture...Mythology of the Empire of the Incas...
I know it maybe isn´t well known but I can give you some info on it.
Like the main god, the creator of all life and universe which is Wiracocha or ¨Apu Kon Ticci Wiracocha¨ that was the main deity in the andean world...It was represented with two bars one on each hand.
Then there is Taguacipa was his main opposite part which turns to be sort of ¨evil¨ or the dark part of Wiracocha which Wiracocha creates he destroys it, which Wiracocha turns to light, Taguacipa turns to dark...
Then you have the ¨Tayta Inti¨ or just ¨Inti¨(the sun itself) which is the servant of Wiracocha, and the ruler of the world...
Then you have the mother, sister, and wife of the Inti the ¨Mama Quilla¨ (which is the Moon, goddess of fertility)
The Sun was mainly a male figure while the Moon was related to the females. The sun represented power while the Moon represented fertility, Wiracocha was the object of adoration of all the people while the Mama Quilla was just reserved for ladies. The sun was represented with a golden circle with rays going irradiatibng from the center, and the moon was represented as a silver half moon...
Then you have the Pachamama (which is the Earth which provides us from our food, goddess of the fertility of the fields and the agriculture) and the Illapa (which is the Thunder, the god of war) there are lesser gods but I need to do some more research on that, I can try to represent and send my impressions on how they look and maybe we can get nice items on that...That could be very interesting to have and wear those items the Incas used to wear, like golden bracelets and pendants, and crowns that can make a good mythological theme...
Ok then I will try to post as fast as I can so I can show my ideas on that...you can search more on wikipedia to expand your knowledge on these gods...
I wish u luck, see ya rofl ninja dramallama wahmbulance
