Legend.
Sudika-mbambi was the firstborn son of the daughter of the Sun and the Moon. He spoke to his mother from her womb and named himself on his birth. Immediately after his twin brother was born, Kabundungulu, both sons rebuilt the house of their parents, which was destroyed by a monster ("makishi") that killed their grandfather. They were both born carrying their sword, knives, staffs, and "kilembe." 
Sudika-mbambi later left his family to destroy the monsters who were responsible for the destruction of their original home. He also worked together with the Kipalandes to achieve his quest, but they later betrayed him when Sudika-mbambi rescued his first wife from perils. He later went on to complete several challenges to marry his second wife, the daughter of the underworld god, Kalunga-ngombe. Though Sudika-mbambi managed to succeed in most of them, an encounter with a legendary beast, Kimbiji kia Malenda, left him mortally wounded. His twin brother, Kabungdulu, sensing that his life is in danger, rescued him and brought Sudika-mbambi back to life.
