Touch of the Illithid
Two drow were out hunting, slowly dwindling down the numbers of the goblins near the city. Something didn't feel right, something was lingering at the back of their minds. They continued to fight their way through the tunnels, alert to the presence of another being nearby they couldn't see. They stopped to catch their breath, and suddenly, a goblin walks past as if they were invisible. Not once, but twice. They decided to follow the goblin, when an illithid appeared before them. Not fully formed, the creature was more of an image of itself. It offered to let the drow join its forces against the city Sshamath, and in return, it wouldn't devour their brains. They refused and it quickly vanished. The drow were no longer invisible, they realized, as a nearby goblin attacked. The illithid still lingered, they knew, as it continued to stroke at the back of their minds.
They managed to capture a goblin attempting to flee and warn its brethren. Uelaereene spoke with it in the goblin tongue, which Xuneera did not understand. After some negotiating, she convinced it to take them to their chief where they would form an alliance to fight the illithid. Along they went. Once outside the Stonespear compound, the goblin guards ordered them to halt while they retrieved their new chief, newly appointed after the previous chief had been poisoned. Chief Pidwick spoke with the drow for a moment, but in the end, he left with clear orders to his kin. They ran a spear through the traitorous goblin that brought the drow and swarmed all over the drow, beating them down until they were barely breathing.
Hours seemed to pass before they regained themselves. They were locked up somewhere below the entrance deep within the Stonespear compound. They tried to bash the door, but it seemed impervious to their magics and weapons. The illithid appeared again, explaining that the cultists originally inhabiting the cave had enchanted their cell door and the wards remained. Xuneera agreed to join the illithid in exchange for their freedom, but the mindflayer added something new to the agreement. It wanted a piece of Uelaereene's sweet essence for himself to feed from. It would not be as painful as they thought, it promised, and the bond would allow the young drow to touch into the illithid's own powers. Hesitant, she agreed, and the illithid opened the door before vanishing. The drow walked out of their cell oblivious to the goblins around them.
Once outside the compound, where they were attacked, the guards still stood their post. As they walked past them, each one fell to its knees in agony before collapsing. Not long after, Xuneera no longer felt the pulling of the illithid. Uelaereene, however, has not stopped feeling it since.
