Kerrigan felt the familiar drop in temperature as she descended into his lair. He liked it cold in his working space, saying that it made his mind more sharp. The painfully chilling air did make Kerrigan more alert, and it was about as refreshing as a slap in the face. She had spend the better part of twenty years aboard this ship, with her only companions being her small crew. Spending this much time with these aliens, she couldn't help feeling close to them, and more detached from her own kind. The elevator opened and she entered his lab, hearing the familiar screams of his failed experiments congealing into biomass. She'd told him before to put them out of their misery, but he had called their pain irrelevant. Abathur was as cold as his lab was, and liked to cause significantly more pain to his victims.
She approached the floor entrance to his lower chamber, and waited for him to emerge. His insectile appendages appeared, stretching up and out of the floor, as he used them to pull himself up. A massive zerg, taller by several feet than Kerrigan, he appeared even larger because of those long, fang-tipped arms on his back. With the body of a massive slug, he also had six arms on his front side, and a shield-like face with eyes similar to that of a centipede. His large front hands came together in front of him, rubbing each other compulsively. A strange being, created for the singular purpose of crafting soldiers for the swarm, his one love in life seemed to be his work.
"My queen. Will serve," he said in his deep, reverberating voice. The large mouth dripped strange fluid from his face, surrounded by small fangs that waved about when he talked.
"You are quite loyal, aren't you?" Kerrigan said.
"Without queen, no purpose. Become feral zerg. Become beast, less," he replied, rubbing his hands together again.
"Good, so I supposed you won't mind me asking for something a bit strange from you," Kerrigan said.
"Queen's purpose, my purpose," Abathur said. Kerrigan smiled, though she already knew he wouldn't say no.
"I need a new augmentation," Kerrigan said.
"Will improve queen," he said, his large back appendages waving slightly in excitement.
"No, actually. You are going to be the subject this time," Kerrigan said. He lowered his head, and pressed his hands together.
"For what purpose? Queen dissatisfied?" he asked.
"Not with your work, Abathur. I decided that I need something more from you, though. It's been a long time since I've been around one of my own kind. There's no one around who can take care of this need I have, besides you. I need you to grow a special kind of appendage inside of yourself. Are you familiar with Terran mating?" Kerrigan said.
"Terrans bad subjects. Mating habits irrelevant," he said.
"I'm making it relevant. I'm going to give you the details, and when I come back I want it completed," she said. He clicked his mouth fangs together as he thought about this.
"Will serve my queen," he said. Instructions were given to him, and despite his evident confusion, he agreed to do as she asked.
