The Eye of the World was a pool of untainted saidin guarded by the Green Man, a nym, in his grove. Who made it?

It seems to shift around the Blight and can only be found through need and is dedicated to plants and greenery. Do you think it was made that way by the AS who created the eotw or do you think they made the eotw specifically there so it would be difficult to find? how does it move around? does it exist partially in t'a'r? if it wasn't made by the AS what was its original purpose? a park perhaps for AOLers?

just thought i'd loose some questions

also i was reading in The World of RJ book how chora trees (avendesora being the last of them) were very commonplace in parks to promote peace and tranquility, do you think that more samples of the avendersora will ever be taken and planted widespread again?
