For centuries all Ethiopian priests need to be educated and/or tested in Debre-Abay to be legit "Mihreys?Memires". Debrekerbe, not far from DebreAbay , Waldiba and Debrekerbe, is where the top echelons of the feudal lords educated their kids.
Debre-Abay was started by Axumite Abune Samuel.
Legit Ethiopian qisina is given only in Debre-Abay, in Tsimbila, Shire.
Waldiba Gedam is not very far from DebreAbay, DebreMenkol and Debrekerbe.
