His face was grave, his eyes concerned. When she looked at him, he squeezed her shoulder. He said to Seremela, “What would you say about the properties of venom to someone who is nonmedical—namely, me?”
The medusa regarded him for a few moments. Her head snakes had slipped over her shoulders to pool in her lap in a coiled mass. Most seemed to have gone asleep, although a few still watched Rune and Carling. Seremela ran her fingers lightly over them. “The very first thing I would say to anyone is, this area of toxicology was not my focus of study in med school, so I can’t speak as any kind of expert. Given that, the properties of venom are extremely complex and can contain different toxins for different cells and tissues of the body. It can also have some surprisingly beneficial properties, such as bee venom treatments for MS patients, or a derivative of a Malaysian pit viper venom to treat stroke victims. Preliminary studies have also indicated that snake venom can slow the growth of some cancerous tumors. It’s a fascinating field of study. So much depends on the venomous species and of course their species of prey.”
“Let’s focus on snakes,” Rune said.
Seremela said, “Mundane snake venoms essentially fall into two categories: the hemotoxic, which is poisonous to the circulatory system, and the neurotoxic, which is poisonous to the nervous system. At the risk of oversimplifying, the snake or serpent species usually intends to subdue its prey.”
Carling looked up. “Your head snakes are poisonous.”
“Yes,” Seremela said. “My snakes carry venom that induces paralysis, although if you take a dose from a single bite, the poison isn’t terribly toxic. A human would experience some numbness and lethargy, along with pain and swelling around the area of the bite. Some might get nauseated as well. Generally there would be no need for a dose of antivenin, unless the victim was a child or went into anaphylactic shock. If I was attacked and my snakes were badly frightened, however, they might bite repeatedly, and that could lead to someone dying. Wyr are more immune than humans. If Rune would consent to hold still and let himself be bitten for a couple of days, the venom from my head snakes could eventually stop his heart.” She looked at Carling. “And a medusa’s snake venom has no apparent effect on Vampyres.”
“What about other serpent creatures in the Elder Races?” Carling asked.
“Well, then you add in the extremely unpredictable element of Power,” Seremela said. “The venom from my snakes is mundane; the snakes are just attached to my head, that’s all. We share a sort of symbiotic connection that has some empathy, a very crude kind of telepathy but no real exchange of language, and the poison is just poison. I really hesitate to speculate about another creature, especially one as Powerful an immortal as Python would have been.”
“The Egyptian priestess you spoke to indicated there was some kind of social contract with the serpent goddess,” Rune said to Carling. “So Python must have interacted with the group. It sounded like there was some level of caring involved, or at least worship.”
“Venom, paralysis, time. Some general themes are coming together,” Carling muttered. “As I recall, the priestess talked about Python caring for her children, giving them the kiss of life that was also death. Maybe Python knew her bite would halt the progression of their mortality. Whatever the motivation or reality, it doesn’t matter.”
“Why do you say that?” Rune asked. His eyes were narrowed.
Carling leaned forward, put her elbows on her knees and dug the heels of her hands into her eyes. She had studied both poisons and sorcery. No wonder her healing spells had only worked to stave off the episodes for a time. The healing spells she had given herself were “cure-alls.” In order to create anything more targeted or specific, she would have needed to know the original properties of what she tried to heal. She said dully, “What exists in Vampyres’ veins mutated a very long time ago. It’s a product of the original source as it interacted with the human immune system. We don’t have any of Python’s original venom, so we can’t create any antivenin.”
“What about a more generalized antivenin?” Rune asked, his voice tense.
Carling was shaking her head even as Seremela said, gently, “For something that Powerful and specific, and for the amount of time you indicated you might have left, I’m afraid that would be an exercise in futility. It would take years of experimentation and drug trials. Don’t waste your time.”
Rune’s tension increased. The force of his emotion blasted along Carling’s nerve endings. She said to him, “I know what you’re thinking. Going back again won’t work. I never met Python, and the episodes are too short for you to go looking for her on your own.”
He said roughly, “I can keep going through until I learn how to go back on my own.”
