Last night I dreamt that two men decided to raise a Gem as their daughter. They had an Era 2 Peridot *not our Peri, just a random one* and their adopted son named Daeryn. The men were also scientists, one of them named Dr. Fuji because I’m also Pokemon trash.
They loosely made a study around raising their Peridaughter and they all lived together for many years. Then Fuji and his husband *I recall at one point they mentioned they were married* started becoming gravely ill. Eventually the Peridot found Fuji dead and her other father near death.
The men died of radiation poisoning, realizing far too late that a Gem’s projected body emits high levels of light radiation.
There’s a headcanon for the toxic *mineral toxicity, not personality* Gems out there.
