“Chlorine gas,” he said.
VenDell grabbed Marasi’s arm. Kandra had athingabout acids.
To Steris’s surprise, they listened to her. Since the powerful ventilators installed in the basement weren’t working, they let her fetch a room fan and set it up. Then they all returned up the steps and stood outside the mansion to allow the place to ventilate. When they went back down, everyone wore their masks without complaint and let her test the air with a kit. From there, they were careful where they stepped as they inspected the room.
The door to the safe box had taken a little jaunt across the room, and was now embedded deep into the thick concrete of the far wall. Thesteel of the box itself had been mangled beyond repair. And the rest of the room…
Well, it appeared that she’dhave to put in an order for a new spectroscope. And a centrifuge. And some more flasks. And… um… new walls…
She resisted her urge to begin sweeping the glass to avert the hazard of stepping on it. Instead she stuck near to Waxillium. He might discover something interesting.
“Rusts,” he said, walking over to the remnants of the safe box. “This thing survived harmonium detonations of up to three ounces. I used less than atenthof that in this experiment.”
He reached for the top of what remained of the box.
Steris wagged a glove in front of him.
“Right,” he said, slipping it on, then feeling around the top of the broken steel box. His hand came away dusted with some black shavings—a fine metal powder. VenDell walked up beside them. Marasi was inspecting the safe box’s door, while Allik had fetched a broom from above and was sweeping up the glass.
Steris had already liked him, of course, primarily because of how he treated her sister. But in that moment, her estimation of him went up another notch.
“We need to test these shavings,” Wax said. “But… I don’t think this is either atium or lerasium. It looks like remnants of iron from the equipment.”
Steris gathered them in some specimen pouches anyway. Waxillium leaned into the broken box on the wall, then used a small file from his pocket to harvest something smoldering inside.
“Harmonium,” he said as Steris dug out an extra vial of oil for him to put it into. “Plastered across the back of the box. I… think the experiment failed. It didn’t divide.”
“Actually,” VenDell said, “I think you managed something far, far more dangerous.” He took out a little notebook. “How much harmonium did you use in here? A few grams?”
“Around half a gram.”
“This explosive force…” VenDell said. “This level of destruction… from such a small sample. It’s possible, but only if…”
“What?” Wax said.
“This explosion was not caused by the division of the metals,” VenDellsaid. “This level of energy release could happenonlyif some of the Investiture or the matter itself was transformed into energy.”
He seemed to notice their confusion, so he continued. “I believe I’ve lectured you at length about the nature of Investiture. It is a particular study of mine. Along with my foremost expertise on skulls…”
“Not for sale,” Wax reminded him.
“Mine is,” Steris said.
Both looked at her.
“Why would I need it when I’m dead?” she asked. “Seems much better to have the money now.”
“As I always say,” VenDell replied. “Your impermanence is outlived by the beautiful internal shells you create—like sand medallions from the ocean, so are the bones of the human being. A lasting testimony of your presence on Scadrial. We shall discuss the terms of your sale at a later date, Lady Ladrian.
“For now, let me be brief. Everything in the cosmere is made up of one of three essences. The first is matter: the physical substances around you. Formed of axi, the smallest possible thing we know.”
“There are things that… aren’t matter?” Steris asked.
“Of course,” he said. “There’s energy.” He waved to the ceiling, where two of the room’s recessed and reinforced lights were still working. “Electricity, heat, light… Your kind has been harnessing it quite well lately. Good for you. Very modern.”
“And the third?” Wax asked.
“Investiture,” VenDell said. “The essence of the gods. Everything has an Invested component, normally inaccessible without certain abilities. When you burn metals, Lord Ladrian, you pull Investiture directly from the Spiritual Realm and use it to do work. Much like energy does work in those lights. But here is the key idea: Investiture, matter, and energy are all thesame,fundamentally.”
