less to play.
I made it legendary just so you couldn't get multiples into play. I was thinking in dandan's thread about how "knight" isn't tied to specific color, and I was about to say, "the creature type Wizard is like this too, except for green, because green doesn't really
study - it prefers to get its knowledge from other sources." Then I started thinking about how green knowledge works.
I don't think it's too powerful. Intuition would break this but it breaks a lot of things.
The flavor is that this should be a large tree, or grove of trees, whereupon green druids and elves scribe the forest's history, an epic tale stretching back hundreds or thousands of years. Possibly the trees themselves could
grow the words right into their bark. This would be an ideal central location for the green part of a plane, when we get into story-building. In fact, I'm thinking of a good plot - black invades and destroys the forest's history, and events proceed from there.
