The third arcanum is about creation. Such a person does not so much carry things out as bring them into being: plans, undertakings, the people around them.
They know how to inspire and do it naturally — beside them, other people find strength and ideas. Hence a particular role in any group: they need not be in charge, but nothing gets started without them.
An important trait is fruitfulness in the broad sense. The third arcanum needs something to grow out of its taking part: a child, a business, a school, a direction.
The weak point is that they find it hard to stop. What has been created needs tending, and they are already drawn towards the next thing.
