Wrth i'r gwynt oer chwythu drwy Gaerdydd, roedd pob un stryd wedi'i hailenwi â'r sêr cyfarwydd o genhinen Bedr.

As the cold wind blew through Caerdydd, every street had been renamed with the familiar stars of the daffodil.

Roedd Gŵyl Ddewi Sant yn agosáu, ac ym Mhencadlys Hedlu Canol Caerdydd, roedd Gareth mewn pryder mawr.

Gŵyl Ddewi Sant was approaching, and in Pencadlys Hedlu Canol Caerdydd, Gareth was in great distress.

Dyma ysgolhaig ifanc a thyner, â'i frown yn crynhoi wrth aros y tu ôl i'r cownter.

He was a young and gentle scholar, his brow furrowed as he waited behind the counter.

"Help," meddai Gareth wrtho'i hun cyn dod at y ddesg.

"Help," Gareth said to himself before coming to the desk.

"Help.

"Help."

"Roedd Arwen yn sefyll yno, gyda nodiadau lluosog ar y bwrdd.

Arwen was standing there, with numerous notes on the board.

Yn swyddog o nifer o flynyddoedd, roedd hi wedi gweld llawer.

A seasoned officer, she had seen a lot.

Roedd ei phen wedi'i phlygu ychydig, golwg sobr ar ei hwyneb.

Her head was slightly bowed, a sober look on her face.

"Rydych chi eto, Gareth?

"Is it you again, Gareth?"

" meddai Arwen, heb godi ei llygaid ar unwaith.

Arwen said, not raising her eyes immediately.

"Beth sydd o'i le y tro hwn?

"What's wrong this time?"

""Dim newyddion o Dylan ers dyddiau," esboniodd Gareth yn bryderus.

"No news from Dylan for days," Gareth explained anxiously.

"Dwi'n poeni difrifol, Arwen.

"I'm seriously worried, Arwen."

"Roedd Arwen yn gwybod am Dylan.

Arwen knew about Dylan.

Roedd e'n ffrind annwyl i Gareth.

He was a dear friend to Gareth.

Fodd bynnag, cofiodd am siom diweddar dros alwad ffug.

However, she recalled a recent disappointment over a false alarm.

Roedd ei thafod yn betrusgar.

Her tongue was hesitant.

"Yn sicr, dyna beth ddywedaist ti'r wythnos diwethaf, pan oedd yn ei daith bryd hynny.

"Surely, that's what you said last week, when he was on his trip then.

Beth os maen nhw'n driciau eto?

What if it's tricks again?"

"Ond roedd yna rhywbeth yn y ffordd y syllodd Gareth arni heddiw.

But there was something in the way Gareth looked at her today.

Roedd wyneb drist a phen pendro, ond ei benderfyniad yn frawychus.

A sad face and a dizzy head, but his determination was frightening.

Dechreuodd hi holi cwestiynau, ond daeth dim.

She began to ask questions, but nothing came of it.

Pan ddechreuodd y gwynt y tu allan godi, roedd Arwen dal yn amheus.

When the wind outside started to pick up, Arwen was still skeptical.

"Mae’n gyfnod stormus erbyn hyn," meddai hi.

"It's stormy weather now," she said.

"Nid yw’r tywydd yn helpu.

"The weather's not helping."

"Nid oedd Gareth eisiau treulio mwy o amser.

Gareth didn't want to spend more time.

Ar ôl oriau dysgwyl, gadawodd y swyddfa.

After hours of waiting, he left the office.

Penderfynodd fynd i chwilio ei hun.

He decided to go look for himself.

Cofiodd am leoliad y car Dylan y tro diwethaf y gwelodd ef - ar ochr hen ffordd tu draw i’r ddinas.

He remembered the last location of Dylan's car - on the side of an old road beyond the city.

Wrth iddo gyrraedd, roedd ei olau gliniadur yn dadlennu'r car.

Upon arrival, the light from his laptop revealed the car.

Roedd y car heb symud, gyda lwc â darn o bapur ar gael uwchben y deialu hanfodol.

The car hadn't moved, with the luck of a piece of paper available above the essential dials.

"Angen brys, teulu mewn angen," yn anniddorol eglurodd y neges arno.

"Urgent need, family in need," the message on it explained uneasily.

Gyda’r darganfyddiad hwn, dychwelodd Gareth i’r gorlan yn llawn o ffydd.

With this discovery, Gareth returned to the station full of faith.

Roedd ei chalon yn canu wrth i Arwen nodio mewn cydnabyddiaeth ar gynnydd Gareth.

His heart sang as Arwen nodded in acknowledgment of Gareth's progress.

"Gwych!

"Great!

Gwnaethoch chi’n dda," cytunodd ganddi.

You did well," she agreed with him.

Wrth ddefnyddio gwybodaeth Gareth, canfu'r heddlu Dylan.

Using Gareth's information, the police found Dylan.

Roedd mewn pentref bach, yn helpu perthynas mewn angen.

He was in a small village, helping a relative in need.

Dychwelodd Dylan cyn Gŵyl Ddewi, gan sicrhau ei fod yn ddiogel a chyfarfod lleol.

Dylan returned before Gŵyl Ddewi, ensuring he was safe and with local company.

Am ennyd, daeth ei fwynhau â'r dyfodiad yn lluosog.

For a moment, the joy of his arrival was abundant.

Gwelodd Gareth drwy’r drysau’r wyneb cyfarwydd yn ymddangos wrth y drefn.

Gareth saw through the doors the familiar face appearing amidst the gathering.

Wrth iddyn nhw gwrdd, trodd Gareth ei gazglwyd at Dylan, gwybod bod ei gredu a’i fhad oedd ganddo.

As they met, Gareth turned his collected thoughts to Dylan, knowing his faith and affection were with him.

Roedd Arwen yn sylwi ar wên mwydo ar Gareth fel roedd llawer o gynnes meddwl.

Arwen noticed a soft smile on Gareth like many warm thoughts.

Roedd yn benllanw da ac roedd pob un ohonynt yn symud gyda'r mynegiant o ffydd mewn cariad.

It was a good climax, and they all moved with the expression of faith in love.

Roedd Gŵyl Ddewi yn gynnar wrth i'w calon symudodd ddim ond bywiog.

Gŵyl Ddewi was early as their hearts moved with only liveliness.
