"Any stranger than meeting a sorcerer who'd been dead for a half century? Or murderous, dead blind men?" Yeats asks.
"Harrington herself? No, she looks to be in her twenties and likely is. There are a few of us who've studied Tera, or at least the texts that are about her. She's not a walking corpse, or anything so vulgar. Not like those blind men Dr. Westcott told us of. No, when Tera died she was truly dead. But in life, she had mastered her ka, her soul. She could, at will, send it out of her body - similar to the Dawn's practices of astral projection," she says to Diggory. "She also possessed in her treasury a huge star ruby, the size of a fist. This she had carved into the shape of a scarab. It served her as a ritual object, used in ceremonies to her goddess, Isis."
Yeats turns his head quickly, but Farr waves off concern. "No, I believe not. Our Mina - Mrs. Mathers - is a ruthless woman and her devotion to Isis is formidable, but I do not think she would ever willingly aid one such as Tera. At any rate. On her deathbed, Tera sent her soul out of her body into the ruby. A few years ago, the Jewel of Seven Stars was found and brought to this very museum by one of the Golden Dawn, a man named Abel Trelawny, and it has since remained under the care of Dr. Wallis-Budge. Until, that is, this Mr. Langan stole it.
"Now as for Ann Harrington. She most likely is one who, indeed, has real power. And by some chance or design of fate, her body was also conducive to Tera's ka. When Langan gave her the Jewel, and she gazed into it, her identity as Ann Harrington was usurped by Tera's soul.
"A very unique being, to be sure. Truly remarkable to have reached this level of magical power without any aid. But this long period of seperation of the soul from a physical body has doubtless made her irreperably insane. I am still trying to figure on where EIECET fits into this. Perhaps he thought to use Tera to aid him. In which case, he is sorely mistaken. Do not ever think to own a woman's destiny, gentlemen." She gives a small smile.
