Death Tentacle Ruins!
During the Mudropper Invasion, one of the refugees fleeing to the Drenta Vines chanced upon it. Upon knowing it was a Ruins left behind by a Mystic Tentacle, the Free Human ventured into the Ruins, only to be never heard from ever again.
His surviving family member, in search of him, eventually tracked the traces to the Ruins too. Eventually, Raid parties were organised to reap benefits from the Ruins, with a majority dying in the process.
However, those who survived reaped immense gains, including a collection of mineral deposits, along with their respective complete cultivation techniques. And when a Human Avatar is built using them, they gain powers that counter the Death Knell Race.
There were specialised Gold Grade minerals, each accompanied by a completed cultivation technique. They were primarily built to counter the abilities of the Death Knell Race, but also had other variants too.
