And like a lot of other things in GOT, this has historical precedent! In 2018, archaeologists excavating a 2,400-year-old burial pit at Tlalpan in Mexico City found the remains of ten people locked together in a bizarre entanglement of flesh and bones that makes your mom's weekly key parties seem downright innocent by comparison.

Upon closer inspection, archaeologists found that all of the grave's occupants were linking arms with their neighbors, while some were linked in ... cozier ways. "There was one individual over the other, for example," excavation director Jimena Rivera explained. "The head of the individual on the chest of the other, the hands of one individual under the other's back, the baby on the body of another."
The handsiness of the dead suggests that they were all related, but that's not (yet) been proven. We also don't know how these people died, or even why they were arranged like this, because this is the first time that archaeologists have found such a burial. Or at least, it's the first time they've been able to talk about it before a curse kicked in and everyone involved with the dig became part of a human centipede.
