Fields of Glass, Mercury
The Gardener's Spire is a location within the Infinite Forest's Simulant Past. The top of the spire is the lair of Dendron, Root Mind. It is only accessible during the A Garden World strike and the A Garden World story mission. The spire itself aids in the transformation of Mercury into a Vex machine world, by using an arc network to poison the life on Mercury with radiolarian fluid.
