I'm not sure as I haven't read it specifically, but usually in a novel about transgression, there could be a rebel - type character who initiates the transgressive acts.
To write a good one, you need a strong conflict based on the romantic transgression. Make the characters' choices have real consequences. Also, use descriptive language to make the reader feel the passion and turmoil.
I'm sorry, but without having read 'transgression a time travel suspense novel', I can't name the main characters. But in a general sense, a time - travel suspense novel might have a main character who is driven by a personal goal or a sense of justice to travel through time. This character could be joined by friends or allies who help them on their journey. There could also be an antagonist or a group of antagonists who oppose the main character's actions in the time - travel realm, perhaps because they have different ideas about how time should be manipulated or because they are trying to protect a certain version of history.
One of the most mysterious Destiny Ghost stories could be the ones where Ghosts seem to disappear without a trace in certain areas. These areas are often rumored to be haunted by an unknown force that even the Ghosts are afraid of.
One of the notable lore locations in Destiny 2's Ghost Stories could be the Derelict Leviathan. It holds many secrets and remnants of past events. The stories told there often involve the fall of the Cabal's once - great ship and how it became a haunted place full of mysteries.
The scariest might be the ones where the Dead Ghosts are found in the Dark Zones. These areas are already filled with danger. When a Guardian finds a Dead Ghost there, it often tells of Guardians who lost their way and were consumed by the darkness. The sense of dread and the unknown in those stories is really frightening.
A really scary one is about a Ghost that got corrupted. It started to lead its Guardian into dangerous and unethical situations. Instead of guiding the Guardian towards the Light, it was guiding them towards dark powers. The change in the Ghost's behavior was gradual, and by the time the Guardian realized something was wrong, it was almost too late.
Well, it could be that not enough people were listening, or the hosts had some personal reasons to stop it. Or perhaps there were copyright problems. Hard to say for sure.
