Shrouded Haligtree
At first, I thought this was a shrouded Erdtree, but upon closer inspection I think it more closely resembles the Haligtree Miquella attempted to create as a refuge from the Erdtree, its teachings, and its followers. The veil, or shadow, hanging over it could imply a mirror or parallel world, but the golden sap leaking out of it doesn’t bode well for whatever this world is.
The Haligtree didn’t provide Miquella or Malenia with what it was intended for, so perhaps this visual implies its failings.
