O dan awyr ddu llwyd yr Arctig roedd y tirwedd yn ymestyn i ffwrdd am filltiroedd di-ri.

Under the gray-black sky of the Arctic, the landscape stretched away for countless miles.

Rhew a snawreu yn ymddangos fel pe baent yn llen anadfer aim, gan guddio'r gwastadeddau wrth resáu dan donnau gwynt.

Ice and snow appeared as if they were an indomitable veil, concealing the plains as they raced under waves of wind.

Dechreuodd Gareth deimlo pwysau'r anialwch oer yn ymledu ar hyd ei gorff, ond roedd e wedi gwneud addewid i'w dîm.

Gareth began to feel the weight of the cold wilderness spreading across his body, but he had made a promise to his team.

Roedd Elin a Branwen yn gwddf-ddiwedd ei antur i ddarganfod hen ryfeddodau cilgant y pridd.

Elin and Branwen were at the end of their adventure to discover the ancient wonders of the crescent of the earth.

Roedd Gareth yn gwybod bod y diben o galon yn allweddol.

Gareth knew that the purpose of the heart was crucial.

Ond cynyddodd y gwynt.

But the wind increased.

Mae'n dod â ffrwydrad o iasau hallt a cryndodau oer i'r carn, gan chwythu dros Elin, a ymladdodd i gadw rhew rhag troedio ar ei sgidiau.

It brought a burst of salty chills and cold shivers to the bone, blowing over Elin, who struggled to keep the ice from treading on her shoes.

Wrth i'r dyddiau fynd heibio, dechreuodd sefyllfa Elin waethygu.

As the days passed, Elin's situation began to deteriorate.

Roedd ei bysedd yn llonydd, fel carden a hongian o'i dwylo.

Her fingers were numb, like a branch hanging from her hands.

Roedd dyn coeg yn siarid â'r arweinydd; roedd dyfodiad marwol.

A mocking man was speaking to the leader; the arrival of mortal danger.

"Mae'r amser wedi dod," meddyliodd Gareth, "mwy na'r genhadaeth yw iechyd Elin."

"The time has come," thought Gareth, "more than the mission is Elin's health."

Gallai gwerthfawrogi'r pŵer yn yr ymateb yn ei feddwl, puesi y dechrau'r amser arall pan adawodd ofn lite tywys ei gyfrifoldebau a ffeilio ei dîm.

He could appreciate the power in the response in his mind, realizing the beginning of another time when fear did not lead his responsibilities and fail his team.

Cafoddistine, yr angen am osgoi digwyddiad drwg.

The necessity of avoiding disaster became clear.

Ffoniodd i envacuation a chaniataodd iddo iddo gael ei faddau gan ddeddf y nhw.

He called for evacuation and allowed himself to be forgiven by their decree.

Nid oeddenohedig, roedd y d'œlni'r chill wedi ei daro Gareth, fe wnaeth cnychu y tîm i ddioddefant.

They were unyielding, the chill's sting had struck Gareth, causing the team to endure.

"Mae ein cyrhaeddiadau'n llu," meddai, "ond mae iechyd ein dîm yn drysor."

"Our achievements are many," he said, "but the health of our team is a treasure."

Pan ddaeth yr ychwanegiad i arbed yr Elin, roedd Gareth yn teimlo cryfder o ysbryd.

When the rescue arrived to save Elin, Gareth felt a strength of spirit.

Roedd yn wybod yn fwy nawr, y hadn't bwyso ar falchder na recordau, roedd nhw'n heldeiniaeth a phŵer y cymuned.

He understood now more than ever, they should not rely on pride or records, but on the solidarity and strength of the community.

Gadawodd e i'r gwyn dyffroli, addawod e i Gymru.

He left the white wilderness, promising to return to Cymru.

Roedd pe bai errill y rhai ar daith arall yn disgleirio o gylch y tîm, fe fyddent yn cofio am eu cwmradau yn hytrach na enw'r cam na neb.

Though others might embark on another journey, they would remember their comrades rather than the name of the step or anyone else.

Mae popeth yn newid, a defnyddiodd e'i dreftadaeth tuag at welliant.

Everything changes, and he used his heritage towards improvement.
