Ascano is a tribal territory within the land of Sapiro. In order to reach this land, one must go through the volcanoes of Lavanea. It is the home of the Barbaros and Gigantes which is their leader, Vish'ka. After Vish'ka's death, Wahid is presumably the new leader. In Episode 167, the New Etherians raided Ascano and forced the Barbaros to come with them, they were hypnotized by Avria once they arrived at Etheria.
