Anjo das Sombras (Em Portugues do Brasil)

The depiction of court politics felt very vivid and authentic. I wonder what research or sources influenced this portrayal?

Their personal ambitions seemed intertwined with the larger social and political forces of the time, which made their actions more compelling.

There were some lengthy scenes that delved into palace life, but I was curious if this was meant to deepen the atmosphere or if it was a challenge of balancing narrative flow.
