Yn y tundra Arctig, gwlad fendigedig yr eira tragwyddol, roedd y gwynt yn chwythu'n chwyrn dros yr ehangder o iâ.

In the Arctic tundra, the blessed land of eternal snow, the wind was fiercely blowing over the vast expanse of ice.

Roedd Aled, anturiaethwr penderfynol, yn edrych ymlaen at y dydd o'i flaen.

Aled, a determined adventurer, was looking forward to the day ahead.

Roedd hi'n gynnar yn y gwanwyn, ond roedd y ddaear eto wedi'i gorchuddio gyda rhew barhaus.

It was early spring, but the ground was still covered with perpetual frost.

Roedd yr haul, er ychydig dros y gorwel, yn taflu goleuni gwan ar wyneb yr iâ blith, yn ei wneud ymddangos fel môr heb ddiwedd.

The sun, barely above the horizon, cast a faint light on the surface of the brittle ice, making it appear like an endless sea.

O'i flaen, roedd Carys a'i thîm yn arwain y ffordd.

Ahead of him, Carys and her team were leading the way.

Roedd y ddau dîm mewn ras gyflym i gyrraedd arteffact hynafol, cudd o dan yr iâ.

The two teams were in a fast race to reach an ancient artifact, hidden beneath the ice.

Arteffact a fyddai'n dod â chyfansoddiad newydd i hanes y tir garw hwn.

An artifact that would bring a new understanding to the history of this harsh land.

Roedd Emrys, cydymaith ffyddlon Aled, wrth ei ochr.

Emrys, Aled's loyal companion, was by his side.

“Ydych chi’n siŵr, Aled? Mae’r eira yn dod yn gyflym,” meddai, bryderus.

"Are you sure, Aled? The snow is coming quickly," he said, worried.

Roedd cwmwl o eira yn tywyllu'r de, gan roi ystyr newydd i'r ras hon.

A cloud of snow was darkening the south, giving new meaning to this race.

Aled frwynai ei ddechreuad anodd a'r dymuniad i ddangos iddo’i dad ei werth.

Aled was spurred by his difficult start and the desire to prove his worth to his father.

“Nid oes gennyf ddewis,” meddai. “Rhaid inni barhau.”

"I have no choice," he said. "We must continue."

Cawsant or-dreulio ar eu ffordd, gan ddal i fynd ymlaen drwy wynt a pupur y gaeaf.

They pressed on their way, enduring wind and the biting cold of winter.

Yn gyflym, roedd y storm yn ei gorffen yn ei llawn nerth.

Quickly, the storm rose to its full strength.

Oren oedd yr haul, lledrithiol o dan orwel yr eira, wedi darfod.

The sun was orange, barely a glimmer below the snow horizon, gone.

Cyrhaeddodd y lle cawr â chledrau sydyn wrth i'r gwynt ganu fel corau o hen straeon.

They reached the massive place with sudden gusts as the wind sang like choirs from ancient tales.

Aled, mewn amrantiad, canfu iddo hithe i'r arteffact.

Aled, in an instant, discovered the artifact.

Ei galon yn lladd yr un dant fel yr un tro cyntaf.

His heart beat with the same excitement as the first time.

Yr arteffact yr oedd wedi hir itheu, roedd o wareiddiad a ddarfododd erioed. Arianol ac amhrisiadwy.

The artifact he had long sought belonged to a civilization that had vanished long ago, silver and priceless.

Y rhannau oedd yn adrodd hanes hynafol, gobeithio i ddod â chyfaddawd a pharch.

The pieces told an ancient story, hoping to bring compromise and respect.

Ond yna, taflwyd i waelod realiti.

But then, reality hit hard.

Roedd y gwynt, yn cael ei chwythu gan gorwynt y storm, yn adrodd stori arall.

The wind, driven by the storm's fury, told a different story.

Roedd y llifogydd o eira yn cau gydag eraill ar och i Aled.

The flurries of snow closed in tightly around Aled.

Doedd dim ffordd allan.

There was no way out.

Yn sydyn, dywedodd Carys, a hithau'n dod i'w resgri.

Suddenly, Carys spoke, reaching a realization.

“Digon! Rhaid inni gydweithio neu byddwn i gyd yn traps.”

"Enough! We must work together, or we'll all be trapped."

Gyda chalon drom, cytunodd Aled.

With a heavy heart, Aled agreed.

Y tylwyth yn cerdded yn ofalus, yn symud fel un.

The group moved carefully, walking as one.

Yn olaf, roedd y storm wedi ildio’i rym i gychwyn y gwanwyn, a’r gobaith oedd yn arwain y ffordd gartref.

At last, the storm yielded its power to the onset of spring, and hope led the way home.

Roedd Aled wedi dysgu bod teyrngarwch a chydweithio'n fwy gwerthfawr na pheidio lloi personol.

Aled had learned that loyalty and cooperation were more valuable than personal glory.

Ac felly, y stori hwn yw mamgu newydd.

And so, this is the new grandmother's story.

Roedd cyfeillgarwch a chydweithrediad yn adrodd hanes yr arteffact a diwylliant pobl oedd wedi i farw, ond nid yng nghof y byw.

Friendship and collaboration told the tale of the artifact and the culture of a people long gone, but not from the memory of the living.

Ymhlith athrawon, roedd y dystiolaeth dan yr iâ, ond o’r un mor ganolog, roedd y ddatblygasaeth ar gyfer yr wyneb i blant.

Among teachers, the evidence was buried under the ice, but equally central was the development for the children on the surface.
