|Examine||A Runecrafting wizard.|
The Great Orb Project activity follows the premise that, when the Runecrafting altars are used, some of the energy in the transfer to the rune essence is lost and then manifests as yellow or green orbs in the surrounding area. Wizard Acantha is of the opinion that green orbs are, as opposed to the yellow orbs, the energy in the rune altars that supply magic. Because of this, she believes that the yellow orbs are useless byproducts that would ultimately pollute the altars.
- Acantha's armrest contains two runes: an Air rune and a Body rune. These two runes seem to power the chair, and acts as a controlling device to move around in her chair.
- Wizard Acantha in her wheeled chair resembles the steampunk machinery seen in the Girl Genius comic book series. Acantha could a play on "Agatha Heterodyne", the main character of Girl Genius who is talented at creating and repairing electrical and mechanical devices.
- Acantha (Greek akantha, "thorny") was a minor character in Greek mythology. She was a nymph loved by Apollo, the sun god. In one version of the story, Acantha refused Apollo's advances and scratched his face when he tried to rape her. Apollo then turned her into an Acanthus plant.
- The Acanthus is a genus of about 30 species of flowering plants in the family Acanthaceae. Hence, the connection with the colour green.
- She shares similarities with Stephen Hawking, who is a disabled physicist that uses an electric wheelchair.
- She is a bit like Windle Poons in one of Terry Prachett's books, before he became undead.
- It is currently unknown why she is bound to her wheelchair.
- Wizard Vief said that she made an elementary mistake on her calculations, then mixed up the green and yellow orbs. This is to imply that she is wrong about the green orbs being good, and he is right about the yellow ones being good.
