Roedd awyr las gyda niwl yn gorlifo dros y copaon yn y Bannau Brycheiniog.

The sky was blue with mist spilling over the peaks in the Bannau Brycheiniog.

Roedd yr haid o goetir wedi ei gorchuddio â dail aur ac euraid, yn carpedu'r llawr fel bod y byd ei hun wedi ei bwytho â phalodau'r hydref.

The grove of woodland was covered with golden and gilded leaves, carpeting the ground as if the world itself had been stitched with the fineries of autumn.

Roedd Gareth yn cerdded ar hyd y llwybr cul, ei galon yn cystadlu gyda theimladau o bryder a dycnwch.

Gareth walked along the narrow path, his heart contending with feelings of anxiety and determination.

Ymhellach wedyn, roedd Elin a Llewelyn wedi aros i gefnogi Gareth.

Further along, Elin and Llewelyn had stopped to support Gareth.

“Bydd popeth yn iawn,” meddai Elin, yn trio ei dawelu.

"Everything will be okay," said Elin, trying to calm him.

Ond roedd Gareth yn gwybod fod amser yn dyngu ei derfyn.

But Gareth knew that time was running out.

Roedd ganddo dasg bwysfawr i gwrdd â hi – adfer oriawr poced arian, hen berl ei deulu.

He had an important task to fulfill – to retrieve a silver pocket watch, an old family heirloom.

Troes y llwybr yn glogwyn serth, a'r tir yn fwy garw ac anghysbell.

The path turned into a steep cliff, and the terrain grew more rugged and remote.

Roedd goleuni'r dydd yn dyddosoli, a niwl tew yn ymledu dros y topynnau.

The daylight was dwindling, and thick mist spread over the peaks.

Roedd Gareth yn gwybod fod rhaid iddo benderfynu aros neu fynd ymhellach.

Gareth knew he had to decide whether to stay or go further.

“Rhaid i mi barhau,” meddai'n lwydrwydd.

"I must continue," he said resolutely.

Estynnodd map hen wedi'i friwsio ac enw'r mynyddoedd wedi'u hysgrifennu dan ei law yn dangos ffordd.

He unfolded an old, tattered map with the names of the mountains written in his handwriting showing the way.

Gan ddilyn llwybr cwt gwynion, plymiodd Gareth ei hun i bol troes.

Following a trail of white stones, Gareth plunged himself into a winding defile.

Tro nesaf, roedd cerrig a blewyn dryllyd yn sefyll fel anghenfilod wrth ei draed.

At the next turn, rocks and bristly hedges stood like monsters at his feet.

Yna, o ddiarhebol yr eiliad, cododd y niwl a llawenodd amlinell y llewyrcaen arian.

Then, in a proverbial moment, the mist lifted and the outline of the silver sanctuary gleamed brightly.

"Yma yw hi!

"Here it is!"

" gwaeddodd gyda'i lais yn atseinio dros y llysnar.

he shouted, his voice echoing over the ravine.

Cysur a gof wasgodd ei ddeinosau pryder wrth iddo godi'r oriawr, goleuni'r pelydr olaf yn neidio oddi ar yr arian disglair.

Comfort and memory squeezed away his anxious doubts as he picked up the watch, the last ray of light leaping off the shiny silver.

Gyda'r nos yn cuddio'r byd o'i gwrlid du, stwffiodd Gareth yr oriawr yn ddiogel yn ei boced.

With the night cloaking the world in its dark veil, Gareth tucked the watch safely in his pocket.

Adlewyrchiad gwydn i'w hynafiaid.

A steadfast reflection of his ancestors.

Teimlodd pwysau'r oriawr yn wresog yn erbyn ei galon.

He felt the weight of the watch warmly against his heart.

Pan aeth yn ôl at Elin a Llewelyn, teimlai newid wedi digwydd.

When he returned to Elin and Llewelyn, he sensed a change had occurred.

Mewn oriau byr o'r diwrnod, roedd Gareth wedi ennill hyder newydd yn ei alluoedd, a hefyd gwerthfawrogiad mwy dwfn o dreftadaeth ei deulu.

In the short hours of the day, Gareth had gained new confidence in his abilities, and also a deeper appreciation of his family's heritage.

Wrth gerdded law yn llaw gyda'i ffrindiau tuag at ddinas y dydd newydd, roedd Gareth yn gwybod nad oedd o wedi colli dim – roedd o wedi canfod llawer mwy.

As he walked hand in hand with his friends toward the city of the new day, Gareth knew he hadn’t lost anything – he had discovered so much more.
