The usual disclaimers apply.
A black-clad, faceless assassin brought forth a sheathed blade. The ornate handle seemed out of place for practical use, but then maybe Ra's preferred to decorate his weapons while dressing simply. The blade he pulled free of the sheath certainly looked deadly.
"Laurel Lance, stand here," he pointed with his sword to the side of a cavern pool.
Nyssa pulled her to the new position when Laurel hesitated. Laurel looked to her friend for an explanation – did Ra's have a specific killing zone or something? – but Nyssa no longer appeared upset. She almost seemed, pleased, at the development. Al Sah-Him rose as the women passed him, but his emotionless mask offered no further insight.
"Remind me, what is your given name?" Ra's asked when Laurel stood alone next to the pool, facing him.
"Dinah," she answered automatically, wondering why it mattered.
"A strong name. Suitable," Ra's nodded, then he pointed his blade at her; "Tonight, Laurel Lance will die, and you will be reborn, Dinah Al Ghul, a daughter of the Demon."
Rebirth? A daughter to Ra's? Laurel wasn't certain if she wanted to laugh or cry. She'd prepared herself to fight if she could, to die if she had to, but this . . . Laurel felt wholly out of her depth. Ra's ordering her to strip off her clothes in the next breath did nothing to improve the situation.
"He doesn't mean completely," Al Sah-Him murmured, stepping closer. After a nod from Ra's, Al Sah-Him helped her disrobe until she only wore her bra and underwear – the more emotional part of her, currently tucked away, was relieved she hadn't been wearing a thong. Standing before a dozen pairs of unfamiliar eyes, Laurel suppressed any self-consciousness at being laid so bare.
Somewhere nearby, League members had begun to play instruments. Two other assassins had ghosted in and rearranged the glowing candles around the pool of water. They'd even added incense. The second Al Sah-Him stepped back, her suit and boots in his arms, a woman began to chant. This was a ceremonial rebirth Laurel realized. While that cleared up her confusion about what was happening, it did nothing to answer why. Her apprehension only grew when Ra's invaded her personal space and pressed his sword tip to the inside of her left elbow.
"Nyssa finds you worthy as a sister. I accept you as a daughter. More than blood, you will be bound to us through the Pit."
Without warning, Ra's drew his blade down her arm to the wrist. He cut his left arm with the same deft stroke. Then he clasped their arms along the bleeding lines. Woozy, she let him help her into the pool; the Pit. The water was warm, comfortably so. "Submerge," Ra's ordered. She obeyed, her head dipped beneath the waterline. Their linked arms were the last to submerge. Then she was surrounded, cocooned in the Pit. A jolt passed through every nerve in her body and Laurel gasped, swallowing water.
