The Grand Cathedral of Life and Death is a perfect masterpiece of live materials as everything that was used to build it are alive. The windows are made from a plant called the Pane Plant which has leaves that are clear and are like windows. The walls are a mix of the vines and roots of the world tree with a plant called the Brick Plants that have flowers in the shape of boxes which also comes in different colors.
The Grand Cathedral of Life and Death have nothing synthetic or made to make it and it will change appearances with the seasons as well. It will truly embody the life and death aspect as the plants made will die in the winter which the outer layer of the church will then be filled with ice and snow. The plants that died in winter will grow back when spring comes and that is what Levin Cloud achieved from asking all of the knowledgeable beings in Alfheim.
