Beachler created different sigils and architecture for each of the Wakandan tribes, with the Border Tribe inspired by Lesotho, the Merchant Tribe having a sigil based on Nigerian writing, and the Golden Tribe using a sun symbol found throughout Africa. Gorilla City, home to the Jabari Tribe, was originally set in a rain forest, but Coogler suggested that it be found up a mountain in snow.[10] Beachler based the written form of the Wakandan language on an old Nigerian language. She consulted with mining and metallurgy experts for the vibranium technology,[16]:15 including for the vibranium mine where the substance is depicted as glowing blue rocks before it is refined into the stainless steel look previously seen in the MCU.
