* They are primarily beings of light and energy. This is emphasized by Meg's observation that their movements are "like shimmering ripples of water." They are not physical beings in the way humans are.
* They are benevolent and wise. They are described as guiding Meg and her companions, offering help and advice. They represent the power of love and hope, in contrast to the darkness of IT.
* They possess the ability to communicate telepathically. Meg and Charles Wallace can understand their thoughts and feelings without spoken words.
* They are able to manipulate time and space. This is evident in their ability to transport Meg, Charles Wallace, and Calvin to different worlds through the tesseract.
* They have a deep connection to the universe. They are described as "part of everything" and understand the interconnectedness of all things.
While we don't know their exact forms, they are likely abstract and ethereal, representing the interconnectedness of the universe and the power of love and hope. They are not traditional, physical beings, but rather beings of pure energy and light, reflecting the mystical and spiritual themes of the novel.
