About not remembering a certain hideout

Hey dudes.

Was traveling from hideout to hide out just doing the regular marketplace grind and I came across a hideout that was amazing to me.

When you would load into the hideout a huge cage like lid would be hoisted off the top of a huge pit in the middle. The pit had skinned humans hung up on the inside of the wall and then a few of them would be released and fall to their knees sobbing.

Could someone kindly identify this for me? I really want to intergrate this into my poe 2 theme

Cheers guys xoxo

Sounds like the Pulveriser Map Device - it was part of the "Merciless Trarthan Executioner" supporter pack, it cant be bought in shop / elsewhere.
