Plot-Triggering Death

""I am doctor Edward Roivas. I am a clinical Psychologist. I am also dead. (...) Their attention turns to my grand-daughter. For she is the last of my line, and the last hope of humanity.""

- Eternal Darkness, Introduction (abridged).

Between the many ways death can be used in media, there's its use as a trigger for the start of the story itself. It could start a Roaring Rampage of Revenge from part of the protagonists and pull them into something even greater, maybe looking for the truth behind the death could make the protagonist know about something he wasn't supposed to know, the protagonist could suddenly see himself having to continue where the deceased left off, or the execution of a baddie may bring forth something even worse, etc.

In order for a death to covered by this trope, it has to satisfy some conditions:


 * The death has to either occur before the story begins, or during the first moments of it.
 * The death must either: 1) Make the plot start moving (without needing to affect the protagonists directly at first), or 2) Make the protagonists start taking some kind of action which later pulls them into the big plot (which must not be necessarily related to the death).
 * In case of TV series or long runners with clear continuity, the death must have affected the big picture of the series. For example, the deaths ocurring on every episode of a murder mystery series do not count; but the death of a close one that made the protagonist take the decision to become a detective so he could investigate the mystery behind that murder does count. Deaths on this kind of works that trigger new mystery arcs also count.

Can sometimes overlap with Posthumous Character, Death by Origin Story, The Lost Lenore, I Let Gwen Stacy Die, Stuffed in The Fridge, Dead Little Sister, Doomed Hometown (can be a greater scale of this trope), and the list goes on and on.

 * The death of Gregory Edgeworth could easily be one of these in the Ace Attorney games. Basically, it was his death that kick started Miles' ambition to be a lawyer, which started Phoenix's. You could even go further back and say that it was 's death that led to Gregory's, and so on. Gregory's death was also the distant catalyst for Misty Fey's disappearance (which in turn had several repercussions on the Fey clan, such as   Iris's father leaving, Mia's Promotion to Parent, etc, Yanni Yogi's , etcetera.
 * In fact, a lot of deaths in this game series have kicked off new arcs and plots (Mia Fey, Magnifi Gramarye etc).
