It had taken her years to find the ruins, but Cara Loft finally stood in the remains of the Moon Temple. Legends told of countless treasures and artefacts hidden in the dark chambers. Carefully Cara moved through the ruined halls, expecting traps at every corner. But all was deathly still and the only sound came from her movements, as she waded through knee deep water. She pushed deeper into the temple, eventually finding herself in a much larger chamber. Dim light shone onto the central altar, upon which rested some sort of crystal staff, partly stuck in mud. Cara waded through the thick sludge, and pulled the staff free.

Pleased with her first find, she stood in the centre of the altar, admiring the wood carving and craftsmanship of the crystal mounted on top. She was about to continue her search when the light in the chamber grew brighter. Cara looked up to see the clouds part, revealing a full moon filling the ritual sky light. She felt something on her hand, and looking down, saw dark slime creeping up her legs. With shock she realised the trap she had feared was all around. She had waded through it for several hours, and knew she could not escape.

The thick black slime spread quickly and soon her legs were totally covered, the sticky substance holding her in place. It had already coated her free hand, gradually creeping over the skin of her arm. Cara heard a noise close to her head and quickly spun to look at the crystal staff. In the bright moon light she could see movement within and she watched with mounting dread as a crack appeared in the smooth surface. More of the dark liquid began to seep from the crystal, covering her hand in the same sticky slime. At the same time a strange glow began to form, and from the corner of her eye Cara could see something appear behind her head, as her clothing changed in the light.

The moon light seemed to power the magic as the staff created a long cloak over her shoulders, merging it with the high collar behind her head. It was a weird feeling, having her clothes tighten and change on her body. The dark fluid continued to spread over her skin and Cara realised that it was bonding to her, turning her body a smooth, shiny black. It actually felt quite good to her and a smile crept onto her lips. It didn’t occur to her that the magic staff was not only transforming her clothing and body but her mind too.

A really old sequence which I've finally got around to scanning. Description is new though.
