The Tiste Edur Warlock King, Hannan Mosag, sent Bruthen Trana to find the soul of Brys Beddict. Bruthen Trana came across an underwater Azath House where he had a glass of wine with Knuckles and Kilmandaros. The two were playing a contentious game with small bones. After a violent outburst by Kilmandaros, Knuckles 'stilled the grains' (ie, stopped time) temporarily so his mother would have longer to look for a pattern in the bone arrangement.
Knuckles accompanied the Errant and Kilmandaros as they schemed to regain the power they once held. Unknown to the Errant, Sechul Lath and Kilmandaros were secretly plotting against him.
It was also revealed that the twins known as Oponn were Sechul Lath's children.
Sechul Lath helped to free the Otataral Dragon, but after freeing her the plan went awry. The Errant fled the chaos, never to be heard from again.
Later, Draconus manifested himself and destroyed both Kilmandaros and Sechul Lath in retaliation for what they had accomplished. As Sechul lay close to death and Draconus had gone, Oponn manifested beside their father in his final moments, promising to track down the Errant and give him a "push" for leading Sechul Lath to his death.
Sechul Lath was revealed to be an Azathanai, the youngest son of Grizzin Farl and Kilmandaros, and the half-brother of Errastas. Described as "weak" and "a follower", Sechul fell under the influence of his older brother. Together, they murdered Karish, the wife of Hood.
