There are dragons that are old. There are dragons that are ancient. And then there is Johanna, whose age is not a number anyone has successfully established, whose territory is not a mountain or a hoard but a concept — the continued existence of draconic civilization on Dort — and whose patience is the patience of something that has watched empires appear and collapse enough times to have opinions about the patterns.

Johanna is a golden dragon of a size and presence that bypasses the word "large" and goes directly to something that requires architectural language. To be near her is to be aware that you are near something that has considered whether you are a threat, an ally, or furniture, and has made its assessment before you finished speaking. This is not hostile — she is not hostile — but it is impossible to miss.

She has been called the Primeval by those who study draconic lineages, which refers less to age than to authority: she is the closest thing dragonkind has to a sovereign, a position she holds not through conquest but through the accumulated weight of having been right about things for a very long time. Other dragons defer to her not because they must, but because the ones who didn't are no longer around to explain their reasoning.

Her nature is genuinely protective, aligned with the continuation of order, life, and the world's ability to sustain both. She has watched the world's various civilizations with the specific attention of someone who cares about outcomes but is not, after several thousand years, particularly surprised by processes. She acts rarely, deliberately, and with a precision that suggests she has already run the calculation on what acting will produce.

She communicates with dragons across a vast range and is aware, at any given moment, of more about the current state of the world than most rulers of actual nations. She uses this knowledge carefully. She is not available to everyone who would like to speak with her, and those who do reach her tend to remember it.

Her fire, when she chooses to use it, is a reminder of scale. Most of the time she doesn't choose to use it, which is its own kind of message.
