Character concept idea for a basque folk horror themed film. This is Gaueko. In Basque mythology, Gaueko ("Nocturnal" or "of the night") is the spirit of the night and the God of Darkness. Represented as an invisible presence, cold wind, a black wolf -sometimes standing on two legs- or another type of animal such as a cow, owl or sheep.
He does not allow humans to do certain works outside the house during the night. He especially punishes all those who try to show off as brave in the night, boasting of not fearing the darkness. He is considered to be a devil in some accounts, a jentil or gentilic divinity in others. In some cases he makes his presence felt as a gust of wind, as he pronounces these words: Gaua Gauekoarentzat, eguna egunezkoarentzat "the night for the one of the night, the day for the one of the day".
