-He explains in a low, breathy, rasping voice-
My trees have not been trees in more than appearance for a long time.
They were originally a hybrid of many plant that i was combining for
asthetic reasons and so that little maintenance would be required to
maintain them. then in later experiments I started making them 'self
maintaining.' and then finally i evolved them to the point that they
maintained the courtyard of the library and in the absense of
caretakers, the library itself.
Today they are more closely related to golems than plants. But they
still retain some of their plant heritage and they still see
themselves as trees. They still can produce fruit, leaves and seeds,
but none of it grows. perhaps they were getting creative as of late
in there attempts to get some of them to grow. I would not be against
you trying your experiment, nor I'll wager would the tree-guardians as
they seem to have been trying to grow more of themselves for quite
some time. Search the recently tilled soils outside for anything that
could be a seed.
When these guardians were still mostly plant, they could produce many
types of fruit and seed.
