Behind the Science: Gaia / Druanna

Behind the Science: Gaia / Druanna Gaia is one of those characters where I think the limitation on her power is more interesting than just saying she can control nature. When Sela reaches Tallus, she meets her as Druanna, the city's high priestess. There's a beautiful garden, she's comfortable in the water, and she knows quite a bit about the people who just walked into her home. You could look at that introduction and assume Sela has finally found somebody powerful enough to solve the whole situation. Then you find out how much it costs Druanna to help anybody. The garden matters because she has been growing it and caring for it since she arrived. She tells Sela that it feeds her and that she's strongest there. That gives you a reason for the setting beyond having a nature character surrounded by plants. This is where she's built up something she depends on. When she later saves Sela, Bolder, and Blake from the city that has turned against them, she gets them out with these golden ribbons of energy. They survive. The garden doesn't come through it the same way. Its plants are dead, and she collapses. I like that the story actually follows through on the expense. We get a rescue, but we also get to see what was spent to make that rescue happen. She hasn't just become tired for a panel and then immediately gone back to doing everything she could before. Her explanation in issue 60 makes the whole thing a lot clearer. Druanna is Gaia, the woman behind the Mother Nature legend in this universe. When she was young, animals were drawn to her and good weather followed her. A fairy explained that Myst's wind, rain, and trees loved her because of the way she cared for them. They wanted to give something back, and the fairy established a connection that let her use their power. There's a very specific distinction here that I wouldn't want to gloss over. In Myst, these parts of nature have consciousness and can willingly offer that power. Gaia also explains that she could control nature on Earth, but Earth's elements didn't have that same will. The comic is giving its fantasy realm a quality that our world doesn't share. The trees agreeing to help her belong to the rules of Myst. That isn't evidence that real trees are sitting around making the same kind of decisions. Originally, that connection let her move between realms and maintain their balance. The Dark One wanted her service, she refused, and he worked out how to cut her off. During the attack, we see the severed head of the fairy who had made the connection possible. Gaia suddenly can't call on her power the way she expects to. The Wolf wounds her, and the Dark One tries to drown her. She's rescued by animals, with a crocodile attacking him and birds carrying her away. That part is important because her later weakness has a cause. Her abilities weren't always this restricted. She survived a deliberate attempt to remove the thing that made them work. An ally saved her using the Orb of Olan. It's the orb on her staff, and it gives her a substitute connection to the power she used to reach directly. But that substitute only allows a fraction of what she once had, and it drains the source badly. That's why the garden can be destroyed helping her save three people. The orb gives her access, but it doesn't remove the cost. If I'm breaking this down from the science side, the useful comparison is the difference between having a source of energy and having a way to use it. Those are separate problems. A device can give you access to something without supplying an endless amount of it. Gaia knows what to do with the power. The orb gives her a way to channel it. The remaining question is whether there's enough available, and whether taking it will destroy whatever is supplying it. Real ecosystems give us a much more grounded version of that dependence. Plants use sunlight to make food, and feeding relationships move that energy through a food web. Change one part of that web and you can affect organisms well beyond the one you directly touched. [NOAA's explanation of food webs](https://www.noaa.gov/education/resource-collections/marine-life/aquatic-food-webs) is useful here because it follows those connections rather than treating each plant or animal as an isolated thing. That doesn't make Gaia's staff a scientific device. It does help explain why a nature-powered character should have consequences that reach outside her own body. There's a physical connection between plants and the atmosphere, too. As the [USGS describes it](https://www.usgs.gov/water-science-school/science/evapotranspiration-and-water-cycle), roots take up water, that water moves through the plant, and leaves release water vapor through their stomata. The plant, the soil, and the air are already participating in the same process. Wind, humidity, temperature, and available moisture affect it. You don't need to give the weather a personality to find a real connection between those parts of the environment. The comic pushes those relationships into outright magic, especially when Tallus is about to fall. Gaia doesn't have enough power left in the plants, so she asks to use Sela as the source instead. Sela has the opposite problem. She has an enormous amount of power and is afraid that releasing it will destroy everyone around her. Gaia believes she can control it, although she isn't certain the staff can handle the transfer. That's a much better setup than having either of them suddenly discover a new ability at the last second. Their existing problems fit together. Sela can supply what Gaia is missing. Gaia has the control Sela needs. They try it, and the result is a storm and a flood that tear through the army outside the sealed city. It works, but Sela is exhausted by the end and says she can't keep going. I wouldn't try to calculate the energy of that storm from a few comic panels. We don't have the measurements, and magic is doing the work the story hasn't defined physically. The interesting thing is that the book still keeps track of where the power is coming from and shows the person supplying it reaching her limit. There's one more detail in issue 62 that I really appreciated. After the battle, Sela helps her restore the garden. It looks like everything has been put back, but Gaia makes a point of saying the original plants are still lost. The new growth hasn't brought those particular lives back. Even with magic, restoring the place doesn't erase everything that happened there. That's a useful distinction when we talk about damage to a living environment, too: making somewhere green again doesn't mean every loss has been reversed. That's what makes Gaia worth looking at beyond the Mother Nature name. She can be tremendously useful without being able to solve every problem alone. The way she uses nature changes after she's injured, the tool keeping her alive has restrictions, and helping someone can consume the environment she spent so much time nurturing. She survives Tallus and agrees to help Sela with Erik, but that promise is interrupted when Belinda takes Sela through a portal. Finding Gaia gives Sela a real ally. It doesn't give either of them a way around every cost or every person determined to interfere.
