Seedlings

It takes a century of soaking in The Pond of Knowledge before a sprout can become an Elder.
We test their brain-pods often, and prune off bad leaves and branches and pods to make room for the good ones.
One elder came up with the idea to graft branches and pods from the wisest of The Elder Council to speed along the process.
The results were a total crop failure. The seedlings and the edler were all destroyed.
Wisdom and knowledge must be earned and learned, not grafted.
The Pond had to be cleaned out and replenished with seeds again.
