Gullet Snake

While at first the gullet snake looks like an ordinary two feet long snake it can be spotted by its small canine teeth. The gullet snake will enter through the open mouth of its prey and start eating them from the inside. They can be grabbed at DX-4 if the victim wakes up in time but pulling on the snake will result in 3 points cut damage to the esophagus on a successful DX roll. This wound will cause -3 to ST, DX, and IQ until healed via time or magic.
Without magic there isn't much that can be done for a victim at any TL below 5 even with those with Surgery available due to possible infection and shock.
