Savania is part of South Pannonia. It's inhabitants called themselves Savans. Before they settled down in South Pannonia they got in touch with different tribes and nations, including Illyrians. They are famous for being isolated from the rest of the world until the Romans occupied their area c. 120 AD. They are famous for believing in gods like Everia, Djona and Konio. They were also gifted in arts and crafting.
Savans settled in South Pannonia probably already in 3rd century BC. They moved there because their god Djona said they needed to spread all over the world.
