I teach children this word at my job and it is fun identifying creatures by when they are most active. Many of the creatures we consider nocturnal at first glance are mostly or entirely crepuscular

Yeah it could be fun. The lich is ultimately just sitting and waiting for them cause he is looking to enter a higher plane through some funky magic but is tethered to the material plane because of their soul. He is literally using the party. This may throw a wrench in his plans a bit

Well in Pathfinder there is a pretty clear delineation between psychopomps and the Grim Reaper so I think we are good there. The SoA actually makes it impossible to revive you so I imagine the soul does not take a normal path into the afterlife and instead gets sucked up by the sphere as well

Hmm yeah you have a point

Well the Grim Reaper is a death, but not THE death

Yeah I was thinking that the half that got sucked in are fighting the Grim Reaper on the edge of Limbo while the half that remained are desperately trying to find a way to bring them back
