Is this all correctly worded?

When Valaran was later returning to her chambers in the Imperial Palace, she was confronted by Nazramin, who revealed to her that he had always known about the relationship between her and Tol. Nazramin told Valaran that he would not reveal the secret to his older brother as long as she would provide him with any information that was sent to her by Tol. Valaran knew that if she refused Nazramin, both she and Tol would be executed, leaving her no choice but to comply with the cruel prince’s offer. The next day, Tol, his personal retinue, and the Daltigoth soldiers departed the capital and began the journey north to Hylo.
