Etruscan mythology
Orcus was the grim reaper, collecting the dead and bringing them to the underworld.
Orcs are creatures of the fantastic universe of JRR Tolkien, that --as many others -- have aversion to direct sunlight, so its activity begins as it gets dark and ends shortly before the first rays of the sun.
If the key word for (134340) Pluto is 'core', then the key word for (90482) Orcus is 'context'.
The aim with (134340) Pluto is to reach the core of our deep inner self to make a personal transformation. After that, we are a new person, and that finally changes our whole word. We have reached the next step in the individual evolution.
With (90482) Orcus, what really matters is the context outside us, which we are part of it. The decision about life or death, about to continue a task or abandon it, are taken depending on the external situation, because with (90482) Orcus the aim is not the individual evolution (as Pluto), but the global evolution of the whole group which we are part of it.
Sometimes the only way to save the people close to us, is to renounce to life (like Silka at the beginning of the movie "Brother Bear", 2004). And sometimes the only way is fighting for life (like Kenai at the end of the movie "Brother Bear", 2004). It depends on the specific situation or context.
