>The Erdtree doesn't particularly absorb people
The people given erdtree burial are in time funneled into its roots and consumed. Topside a red visciousy residue of resin leaks from the roots of the tree. It's eating people to power itself.
Nightreign isn't connected to Elden Ring's plot but it is related to Elden Ring's overall world. The grace that Marika has control over is coming from some sort of excess overflow from the Nightfarers you see that in all their endings.
