I: Giant Celestial Yellow Crystal

These look amazing, and even blown up (over 33m tall) the land impact was very reasonable (around 14 Li)! Fully mod, and most importantly the scripts are mod, so you can adjust the rotation speed of the pieces to your preferences. Particle emitters and so on can also be removed if you prefer. These are seriously quality and should be in your inventory if you want fantasy, steampunk or any other theme where they'd fit!
