Gahutu, eponymous ancestor of the Hutu and the son who failed the vigil by sleeping and was set to serve his brother. Authored as a son (parentId) of banyaruanda_kanyarwanda and sibling of banyaruanda_gatutsi and banyaruanda_gatwa (reciprocated in-batch). VARIANT: a parallel tradition makes the three the sons of the first man Kazikamuntu (banyaruanda_kazikamuntu) instead of Kanyarwanda (still others name Gihanga or the celestial Kigwa); documented here but only the cluster parent Kanyarwanda is wired in parentIds. Type = mortal: an eponymous TRIBAL FOUNDER (authored mortal by rule), descent otherwise computing to scion (quartigod father 0.25 + mortal unregistered mother 0, /2 = 0.125) with a parallel strand of mortal descent from Kazikamuntu — lower tier chosen. era heroic-age = the cluster era.
