The First Note

After Diathorus finished speaking, he raised his head and looked at Roy hopefully, waiting for his answer. But Roy was noncommittal about his proposal and remained silent.

He could understand Diathorus very well. After all, Diathorus should be the first batch of prisoners after Sargeras established the prison of Mardum. He had been imprisoned here for more than a thousand years. Even a demon with a long lifespan would probably not be able to bear it. It was normal for him to want to break out of the prison and escape after such a long time. But with his strength, it was impossible for him to break through the spatial blockade of Mardum, so he placed his hopes on Roy, this demon king.

In other words, Diathorus hoped to use his loyalty in exchange for Roy taking him with him when he broke out of the prison.
