The Oxygen Chasers
Posted also on A03
When mankind had learned to walk backward through time, the first law was not awe.
It was paperwork.
No one went into the deep past by whim. A scholar who wished to set foot in dead ages had to give name, oath, blood-scan, grant trail, risk ledger, field aim, return plan, death plan, and six hundred pages of blame laid out in clean black marks. Three boards read the work. Two more boards read the readers. Every question bred three more questions. Every answer had to be stamped, countersigned, sealed, and sworn.
This oversight did not keep fools from foolish acts.
The boards knew of the games. Everyone knew of the games. No form had a box for them. No hearing chair ever asked whether a field team had wagered a month’s pay on who could land closest to the start of the the great Breath-Rise. without gear and still come home breathing.
To ask would have made the thing real.
So the boards turned their faces aside, stern as stone, while young doctors of time and bone-lore drank too much in basement halls and spoke with bright eyes of old air, green seas, red skies, and death at the edge of breath.
There were rules, though no one wrote them.
No exo-gear. No sealed lung-rig. No hidden blood-boost. No nurse-drone under the cloak. One witness. One clock. One step down, one breath taken, one hand raised before the jump-back.
The old brag was simple.
How far back can you go before the world kills you?
The first man to try it with any fame was named Harl Venn, though in most mouths he became only Harl the Hen-Man. He was not a sound scholar, but he had tenure, three dead marriages, and a pet thought he would not loose: that tyrant lizard flesh would taste like chicken.
He said this so often that men began to dare him toward it.
He went.
The record, sealed in a black file under four locks and one false name, showed ninety-one seconds of wet heat, buzzing flies, and Harl Venn laughing through his mask-clip before the mask-clip came off. It showed him cutting a strip from a fallen carcass in a fern brake, holding it over a hand-flame, and taking one hard chew.
He did not smile.
The thing behind him moved before the witness could shout.
The boards buried the tape. The basement halls did not. For three years afterward, any meat served in the south wing was met with someone lifting a fork and asking whether it tasted like Harl’s chicken.
The second death should have ended the game.
The third should have ended it harder.
By the tenth, even the drunkest bone-men had begun to give the stegosaurs a wide berth.
There was something almost shameful in it. Mankind had split time, chained paradox, mapped safe windows through ages no eye had seen, and still lost learned folk to a tail full of spikes because someone, somewhere, had said, “Closer.”
The word for the killing end was old, half-joke and half-memorial: Thagomizer. The dead had not found it funny. The living found it funny because the living were still breathing.
After that, the game changed. It grew quieter. No more boasts in the bright halls. No more open wagers. The stakes moved into old message strings, hand-carried slates, scraps burned in sinks. Names went out of the telling. Only numbers stayed.
Closest unguided step into high-carboniferous swamp: fourteen minutes, nine seconds, with lung scarring and one lost boot.
Oldest naked-hand soil touch: one billion, nine hundred million years before present, under shore-light dim as ash. The hand blistered. The hand lived.
Earliest no-gear breath: disputed. Three claimants. One grave. Two sealed hearings.
By then the forbidden work had thrown off more truth than half the clean grants.
They knew which old airs bit the lungs slow and which bit fast. They knew the taste of iron in a young sea wind. They knew what spores made skin swell, what insects drove a grown scholar to claw at his own faceplate, what quiet water could hide a jaw, a spine, a bloom of poison. They knew that some eras killed with teeth, some with heat, some with air that looked harmless and went into the blood like a knife.
They knew, too, that none of it could be printed.
A paper needs a method.
A method needs a field record.
A field record needs a reason why Doctor So-and-so, sworn fellow of the Ninth Chronologic Chair, was standing bareheaded in a Devonian marsh at 03:12 station time.
So the findings slept.
They slept in locked drives, in misnamed folders, in jokes told too softly, in scar tissue, in lungs that never fully cleared. They slept in the hands of gray scholars who had outlived their wildness and now sat on the very boards they had once slipped past.
When young applicants came before them, bright and clean and hungry for dead worlds, the old ones read the forms with care. They marked weak tether plans. They struck down loose sampling aims. They asked for stronger masks, better return locks, clearer death clauses.
And sometimes, when a candidate asked why the rules were so hard, one of the old board members would look over the rim of their lens.
They would not speak of games.
They would not speak of Harl Venn, or the tenth Thagomizer, or the woman who came back from the red shore with one breath left and blood at both nostrils.
They would only tap the paper with one bent finger and say, “The past is not waiting for you.”
Then they would stamp the form denied.
