Hadrea: "Yes, there are some crystals here." *Holds up an Ender Pearl* "When we build up a lot of Ender energy, over time these crystals, which we call Ender Pearls, form in our bodies. When they start to get big, we have to push them out of our chests carefully. When we die, if there's one formed inside of us, it'll be left behind. If it's infused with enough Ender energy, we can be revived. Some people throw them to teleport, but Ender Pearls are fragile, so they end up breaking as soon as they hit something."

Hadrea: *Gets up. Goes to the window. Points up to some black pillars with glowing purple crystals on top. "Long ago, before we looked like this, the Dragons of the End made those crystals. They contain the Dragon's energy. Before he was killed, the male Dragon used them to heal himself when he fought against invaders, but one of them broke the crystals, which let the invader kill him. At least, that's how the legend goes."

Keriann: *Points to some crystals decorating the house* "We also bring crystals from other worlds here. Lots of them look really nice, so we bring them home with us. We can feel some kind of power coming from some of them, but we don't really care about that, so long as nobody gets sick."
