The Fir Tree is a decorative agent by The Second. The tree can by changed to one of five sizes and is invisible to creatures. When first injected, the tree has a red border to show that it is in 'grab mode' and can be picked up and moved around. Shift-clicking cycles through the different sizes. Clicking locks the tree into place and removes the red border, but clicking again will unlock it so that the user can move it again.
