The Riddler returned, and guided Theo - "Theopho Rahadi, previously Theopho Lebanel" - through the stacks. He learned several things.
"Emissary" is an unusual and nonspecific title; a more precise and well-understood one for Erecura's position in life would be "high oracle". She was not a formal priestess but the most powerful of diviners in Pharasma's service, and the one consulted by the formal priesthood when they required guidance more specific than doctrine and more reliable than hoping for a vision. Erecura was favored enough to occasionally receive visions by being bodily transported to the Boneyard, which she ultimately used to set up her act of theft.
In life, she had a persistent wasting disease no magic could cure. This was considered her curse, which most prophets and prophetesses possessed; great power, but with a price. Beyond other spellcasters of her (considerable) power, she had power not just to see through time but to manipulate it.
Despite her power over time and her obedient service to the Divine Queen of Prophecy, her death of age approached, inexorably. Not directly tied to her patroness in her mind, her growing resentment went unnoticed by the Lady of Graves. But since she had visited the Boneyard bodily in visions, she was far more able to transport herself there than almost any other mortal. And one day, piecing together scraps she had seen there, visions she had received, and lore she collected, she perceived that in a room she had visited, Pharasma kept, well-concealed but weakly-guarded, seeds of divinity, fragments of dead gods and failed ascensions.
Stealing from these seeds would cure her mortality, and her wasting disease. It would also make her a godling, which seemed like an interesting and useful thing to be, upgrading to 'very important thing' when she contemplated the near-certainty that her theft would be discovered, if not immediately then at some later point during her (now eternal) lifetime. And Pharasma's opinion of those who tried to defy death was, then as now, extremely clear and well-known.
She planned for three years, three months, and three days. She spoke to a mystic theurge of Nethys and, together with her, devised a spell that channeled prophecy not through its reigning goddess Pharasma, but entirely and specifically through the Mad God Nethys. She created a bubble of Time-Out-Of-Time, and within that bubble cast the spell to determine when to strike.
She struck, she intruded, she stole. She ascended. She was caught. She was condemned.
For the next millennium and more, she was the goddess of prophets and oracles. Not of prophecy; Pharasma kept dominion over that. But she had dominion over those who proclaim prophecy. Pharasma might send them visions, but she would ward off dangers when they were recovering from them, and help them stave off madness from seeing too deeply into the prophetic depths.
She gravitated to Dis, the most civilized portion of Hell to her sensibilities. Asmodeus and Dispater cultivated her for her insight into the future, her skill for predicting the unknowable and seeing, while unseen, that which could not be seen. She flourished in adversity, and built a jungle garden within Dis's walls. And then, after many centuries, the garden became a palace: Dispater courted her, and won her affection and her hand in marriage.
Then Aroden died, and the Age of Lost Omens began. Now there were no prophets, no oracles of the future. She was reduced to governing soothsayers. But a major god lay dead for the first time since the Starstone fell, sundering a world in his death throes. Gods, it seemed, were weaker than they appeared. The time was ripe for one of her old traits to come to the fore, the elevation of a new domain.
Erecura was not merely the Speaker of Auguries and the Flourisher-In-Desolation. She was also the Thief of Forever and the Emira of Hubris.
Pharasma was said to hiss with rage, because she could not condemn Erecura further without undermining her own authority. True or not, she enforced no punishment on her wayward servant beyond what had already been in place.
Theo felt an immense kinship. Here was a goddess he could have served, if the Laws of Man had not already claimed his heart. Spit in the old bitch's eye, and turned the spiteful retaliation into not just one victory, but two. Damnation, he almost wished she were unmarried so he could proposition her. It probably wouldn't work, he was no Cailean, but then she wasn't Calistria either. Also that would definitely get him kicked out of Rahadoum even if he was the dom in the relationship, which, let's be fair, was unlikely.
He thanked the Riddlers, confirmed that he was born to Noble House Lebanel rather than some other family with that surname, and departed to pack his final bags for the trip back to Manaket.
