For a long time in the game's development Clua was not Lanoa's old dead aunt in the visage of a mask.
Originally she was a young fairy similar to Navi from The Legend of Zelda Ocarina of Time. But I wanted to make Clua more original and have more depth so I eventually abandoned this design in favor of the one you see in game.
The earrings I gave her in this drawing are Fulani gold earrings. The Fulani live in various countries in West Africa. Interesting thing to note is although Clua never got to wear these earrings, I brought them back for Nziru's design in Nsala Sunset.
