My party had the idea of using Transport via Plants to bring people to the druid, but I'm a bit unsure if that's possible.
This spell creates a magical link between a Large or larger inanimate plant within range and another plant, at any distance, on the same plane of existence. You must have seen or touched the destination plant at least once before. For the duration, any creature can step into the target plant and exit from the destination plant by using 5 feet of movement.
The spell specifies that one Plant becomes the target and one becomes the destination. Does the "target" tree have to be the one in range of the casting, or can you make that one the destination, and set the entrance to a tree somewhere else?
