Biography
He was born as Rodny, but later changed his name to Bernard after erasing the memories of everyone in Silo 18. While training under Mr. Wyck to be the next Silo head, he used unwitting porters to deliver and detonate demolition bombs at various levels in the Silo, causing farmers to get revenge by burning down porter depots and mass murdering all the porters inside. He then discovered that a vengeful elementary school teacher was the root cause of the never-ending cycle of violence, by spending a hundred years teaching young children to think for themselves and follow their dreams. It was revealed in Shift that Rodny and Mr. Wyck contributed to the violence in order to "reset" the silo, since the only way to erase people's memories was to use a drug in the water that prevented them from recalling bad memories.

In his first appearance in Wool, Bernard is revealed as the true ruler of Silo 18, responsible for all the murders and violence during the events of Wool. After exiling Holston and Juliet to a toxic wasteland and covertly murdering Mayor Jahns and Deputy Barnes, Bernard had security gun down an angry mob full of mechanics and warehouse workers, and then bombed their barricade when they retreated.

However, after Juliet survived the cleaning and re-entered Silo 18, it was revealed that Bernard was only the puppet of Thurman, the true ruler of Silo 18. But in reality, Thurman was actually Donald posing as Thurman, who had his ex-wife Anna hack their cryopods and switch their names. Donald then had a mental breakdown due to claustrophobia and killed his ex-wife and attacked Thurman, but this only caused Thurman to wake up, regain control, beat up Donald, and kill most of the people in Silo 18 by opening the airlock. This also killed Lukas, who Bernard was training to be the next head of Silo 18.
