| —Ori and the Blind Forest |
The Water Vein is an ancient gemstone, designed to grant access to the Ginso Tree. The gemstone is spherical in shape, and gives off a light blue glow. In game, it's approximately the size of Ori.
Out of all the different Keys in Nibel, the Water Vein has the longest uncollected appearance. Its screen time is drawn out by Gumo, who steals the Water Vein and repeatedly flees Ori.
