In less than ten hours, they would arrive at Serpent's Grave. If he could have drained his core dry to push Sky's Mercy any faster, he would have—his wife and son were waiting for him down there. They'd left their home back in the capital to follow him, and then he'd abandoned them for two months to chase down their delinquent Underlord.
This was his job now, however much it strained him to be away for so long. Eithan was the reason he'd been able to marry Jing in the first place; only an Underlord’s word had convinced their families to agree to the match. Even putting up with Eithan for the rest of his life wouldn’t be enough to repay that favor.
Though he had taken Cassias’ place.
Cassias was born to be Patriarch of the Arelius family. He was a direct descendant of the bloodline, his appearance and conduct were impeccable, and from an early age he had impressed everyone with his skill in the sacred arts.
But none of that had been good enough for Jing’s family before Eithan took his side. He’d traded away his position as Patriarch’s heir with a smile on his face, but the occasional reminder could still…sting.
Eithan yawned and shut the book. “Nothing but clear sky between us and a safe landing.”
A web of invisible power stretched throughout Sky's Mercy, bringing Cassias little snippets of information: Fisher Gesha's sheets rustling as she turned, Yerin's eyelids crinkling in a disturbing dream, Lindon's chest rising and falling evenly. There was no privacy when an Arelius was around, but it was polite to act otherwise.
Everyone knew what the Arelius could do, but they didn't know about the limitations. Publicly, the family liked to pretend they had none.
Now that he'd confirmed the outsiders were asleep, Cassias spoke freely. “They can’t hear us. Tell me when we’re really close enough for you to guide our landing, please.”
He’d known Eithan for six years now, and worked closely with him for most of that time. He could tell when the man was bluffing. Usually.
And one of Cassias’ first tasks after Eithan’s arrival had been to determine the limit of the Underlord’s senses.
Stretching, Eithan spoke through another yawn. “My father used to say the First Patriarch could watch over his descendants from another continent. Maybe even from…beyond the grave.” Eithan waggled his eyebrows up and down.
“Do you often listen to myths?” Cassias asked lightly.
“Yes. That's the secret to reaching Underlord: studying old tales. That, and bladder health.” Eithan headed to the back, to the side of the bar. “If you'll excuse me, the house can fly itself for a moment.”
Cassias was left alone in the central room of Sky's Mercy. It had been his home for the last two months, and over the course of his life he'd spent even longer inside, but he'd grown up expecting it would belong to him.
Now, it was Eithan's. Cassias was only borrowing it.
Everything in life was a trade.
Before heading upstairs to his own bedroom—there were six aboard Sky's Mercy, as well as the washroom, the bar, a training room, and a silent chamber for cycling—he stopped.
Over the month since departing the Desolate Wilds, he'd built up a certain curiosity. Now that the other three were asleep, and the two children had both left the circle of wooden dummies alone, he had a perfect opportunity to indulge that curiosity.
Eithan would know what he was doing, of course, but it was best to operate as though Eithan knew everything. The Underlord could stretch his web to a target miles away, if he was focused on a specific spot, but he saw everything within a hundred yards without even trying.
Cassias pushed the door open, took two steps on cloud through the bitter, cutting wind, and entered the repurposed barn.
Only slanting bars of moonlight cut through the shadows, but Cassias could see all eighteen dummies with his bloodline powers. An arm here, a slice of head there, a piece of a circle, but it was enough for him to fill in the gaps. As he moved, strands of his detection web swept through each of the dummies in turn. It was as though he could run his fingertips over everything in the room, slowly gaining a picture.
He finished in a few seconds, confirming what he'd suspected. Because he knew Eithan was listening, he shook his head and sighed.
“You're not trying to kill him?”
When he re-entered Sky's Mercy, he found Eithan standing at the control panel. “Of course I'm not,” the Underlord responded. “When a mother bird pushes a chick from the nest, is she trying to kill her child?”
“That's a Lowgold course,” Cassias said, his tone dry. “I trained on something similar until only a few years ago.”
“It should be similar indeed. I took the plans from your training room back in the main house.”
Cassias cast his web back over to the barn, sweeping his sensations through the dummies. It wasn't as quick or as detailed as it had been when he was standing an arm’s length away, but it was still thorough.
With very little surprise, he realized Eithan was telling the truth: the two courses were virtually identical. It would be a relief if he ever caught the man in a lie instead of a half-truth, bluff, or exaggeration.
“You're teaching a child to wrestle by locking him in a closet with a wolf,” Cassias said. His tone straddled the line between polite subordinate and stern caretaker.
He had gotten to know Lindon over the last few weeks—the boy was earnest, quick, and almost entirely ignorant about the sacred arts. Cassias didn’t want to see him hurt.
Someone had raised him completely disconnected from the real world, and he needed a thorough, solid education. It would take years to prepare him with all the knowledge he needed to face society, especially as a representative of the Arelius family. Their enemies would tear him apart, if he weren’t ready.
Eithan seemed determined to cram those skills into him in a matter of months. That wouldn't help him or stretch him; it would burn him up like dry tinder.
“Jai Long is dangerous, even for a Highgold. Best to start Lindon on something as safe as a wolf, wouldn't you say?” Eithan was sitting on the control panel, reading his book again as the night sky stretched out the windows behind him. He didn’t even bother to face the glass.
“You really want him to fight against a former Jai clan heir? Still?” It wasn’t technically proper to question the Underlord, not even in private, but Eithan had never been one to lean on propriety. Besides, dealing with him was a trial that would stretch anyone’s manners.
Eithan flipped a page. “You've been watching Lindon and Yerin both. What do you think?”
“Yerin is a treasure vault,” Cassias said immediately. “I can't imagine completing a Lowgold training course using a Goldsign like hers, but she almost has it. Her madra is incredibly stable if she really reached Lowgold only a few months ago, and at this rate she could reach Highgold inside a year. She was born for the sword arts.”
“Not just born,” Eithan said. “Made. And Lindon?”
“He's...talented,” Cassias said hesitantly. In truth, he didn't know what to make of Lindon's ability. His mind and attitude were admirable enough, but his spirit...
He had two half-sized cores filled with Iron-quality pure madra, a few very interesting trinkets in his pack that Cassias had respected his privacy enough to ignore, and an Iron body that was far beyond his capacity to support.
He knew Eithan must have led Lindon to that particular Iron body, but he didn't know why. Lindon having to carry that body was like a child trying to control an Underlord's weapon; they might be able to flail it around a little, but in the end, it would do more damage to them than to anyone else.
