From the update:
Finally, the Bone General Expansion Upgrade will be followed by a second Heavenly Creature. More details to come, but there is some confusion in the comments that we did not anticipate. The core game already includes Kei Lun, our first Heavenly Creature. He is the largest miniature in the box, about 125mm high and he is gorgeous. Ray is adding the finishing touches and you will see him soon. But the Heavenly Creature in the Stretch Goal is not Kei Lun, it is a different Heavenly Creature. Be careful, here be dragons.
