The dragon is the only one of the twelve that doesn't exist, and that fact is the explanation: it stands not for an animal but for scale and imagination. It holds 辰, seven to nine — the hour the day is properly running and things start getting bigger.
You'll recognise it here: small subjects make you idle, which is a sizing problem rather than an attitude one; you need meaning, and without it you won't even start; and you get pushed to the front in groups without competing for it.
Running well, the dragon is whoever opens the scale: while everyone is costing the detail, you ask what the largest version of this looks like, and that question frequently changes the answer. Blocked, it goes two ways. One is height without hands — everything thought large, the landing work undone, so it all stops at vision. The other is treating being misunderstood as proof of being special. The dragon's practical lesson is finding the people who'll do the detail and respecting them: you supply the height, and without a foundation the height is only a number.
