Ajuangan, but it is an interesting idea.
The odu Osá-Ogbe offers a similarly intriguing possibility: one tratado says that here Asojano prepared his “pot of witchcraft,” which he called Ibako. After wrapping it in black and white cloth, he fed it some nasty stuff.
Another tratado calls Ibako the “witch” of Oluó Popó; Ibako is supposed to live in the forest, buried at the foot of an Araba tree. Like Asojano, Ibako is an ambiguous mixture of elements: he takes an ancestral relic but he also takes stones. Like Ajuangan, he is explicitly referred to as an oricha. To consecrate him, you must sing many songs for Osain and Asojano.
I know Pedro Abreu—Asonyanye has given Ibako to his godchildren at times, though I don’t really know how he decides who should have Ibako and who should not. Abreu calls Ibako “the prenda of Asojano.”
