Y bore hwnnw, cyn i'r haul godi'n llawn dros y stryd dawel yn y faestref Fach Gymreig, roedd y tirlun eisoes wedi’i drawsnewid.

That morning, before the sun fully rose over the quiet street in the small Welsh suburb, the landscape had already been transformed.

Roedd y byd o gwmpas Eira wedi ei drwytho'n wyn yr eira cyntaf.

The world around Eira was soaked in white from the first snow.

Roedd trionglau siâp teg a blinkau disglair yn amgylchynu ei gynefin difyr.

Beautiful triangular shapes and sparkling twinkles surrounded her lively habitat.

Ond heddiw nid oedd hi'n gwyro popeth yn gyfarwydd.

But today, not everything was familiar.

Roedd Eira wedi cynllunio popeth i'r eiliad, fel yr arferai, ond doedd dim wedi paratoi ar gyfer yr eira annisgwyl hwn.

Eira had planned everything down to the minute, as she usually did, but nothing had prepared her for this unexpected snow.

Daeth Rhys i'w hochr wrth iddi gyffwrdd y ffenest, gan wylio'r flociau eira fel seren cyfoethog.

Rhys came to her side as she touched the window, watching the snowflakes like rich stars.

"Mae'r ffordd allan wedi cau," sylwodd Rhys, gynnes a sipio eu coffi Cymreig.

"The way out is blocked," noted Rhys, warm and sipping their Welsh coffee.

"Gellid bod y cyfarfod pwysig yn methu'r wythnos nesaf," meddai Eira â brysurdeb yn ei llais.

"The important meeting might miss next week," said Eira with urgency in her voice.

Roedd cytundeb mawr i'w gynnal, a rhaid llyfr i'w cyflwyno.

There was a major contract to be held, and a book needed to be presented.

Heb y pecyn hwnnw, byddai’r cyfwelydd yn aros, ac roedd ei swydd mewn perygl.

Without that package, the interviewer would be waiting, and her job was in jeopardy.

Yn sydyn, clywodd sŵn uchel o'r tu allan.

Suddenly, she heard a loud noise from outside.

Yno, wrth y drws ffrynt, roedd Gwen, gydag eira gwyn ar ei clytiog siâp bach arbrawf.

There, by the front door, was Gwen, with white snow on her patchwork-shaped little apron.

"Beth am hyn?

"What about this?"

" rhaib Gwen yn llon, yn edrych ar yr hen sled pren defnyddiwyd sawl gaeaf yn ei phlentyndod.

laughed Gwen cheerfully, looking at the old wooden sled used many winters in her childhood.

"Yr hyn sydd ei angen ar Eira ar hyn o bryd yw antur," meddai Gwen â gwên o danochog wrth Eira.

"What Eira needs right now is an adventure," said Gwen with a teasing smile towards Eira.

Roedd ei nghalon dal i gystwyo.

Her heart was still racing.

Datblygai drwodd gollegeiddio'r sefyllfa, gwres yr unfed awr bryfocach nag erioed o'r blaen.

She unfolded through analyzing the situation, the warmth of the moment more enticing than ever before.

Ond gwyddai mai'r trenau oedd wedi eu cefnu ac am y ddau ohonynt, dim ond ffordd syml ar draws y parc yn aros i'w oel.

But she knew the trains were stopped and for the two of them, only a simple journey across the park awaited.

Wedi eiliad o ansicrwydd, yn ôl eu dewisiadau arferol, bugeiliais Eira gyfanswm y pecyn yn ei breichiau diwethaf, teimlodd fod popeth wedi'i paratoi'n dda.

After a moment of uncertainty, back to their usual choices, Eira shepherded the entire package into her arms at last, feeling that everything was well prepared.

Rhoddodd Gwen weddill Eira’s mawrder i’w harwain drwy strydoedd wedi'u gorchuddio ag eira'r parc.

Gwen gave the remainder of Eira's grandeur to guide her through the snow-covered streets to the park.

Y ffyrdd arferol oedd yn annigonol ac roedd chwibaniad ffres yn cyflawni'r cyflwyniad.

The usual roads were inadequate, and a fresh whistle accompanied the presentation.

Cafodd Eira ei gwblhau trwy'r eira, y sled yn dywyllu'n ysgafn ac yn syml.

Eira was completed through the snow, the sled gliding lightly and simply.

Llwyddodd i gylchdroi drwy'r sleidr yn ddeheuig mewn môr o ddaear fwy gwyn.

She managed to navigate the sled skillfully in a sea of whiter earth.

Pan gyrhaeddodd Eira swyddfa'r gyfarfod yn llawer o lan a chynulleidfa, roedd hi a'r pecyn yn ddiogel ar gyfer eu lles.

When Eira arrived at the meeting office, much to her relief, she and the package were safe for their success.

Daeth eiliad o dawelwch ar ei hôl, ac echdwyd o lwyddiant.

A moment of calm followed, and they burst with achievement.

Glanach brysiog gyda lefel jersey llawn, diswyddodd rysáit y llwyddiant.

A brisk cleaner with a full jersey level dismissed the recipe for success.

"Eira, wyt ti wedi dod â'r werthfawrogiad mwyaf," meddai Rhys yn lled â gwybodaeth wyddonol, pan ddychwelasant oddi wrth ei hanediad llon.

"Eira, you've brought the greatest appreciation," said Rhys jovially when they returned from her happy command.

Yn achos wedi'i gwblhau am y cyntaf, roedd Eira yn teimlo'r freiniol hapus bod y byd wedi ailymateb ati.

In a case completed for the first time, Eira felt the privileged happiness that the world had responded to her.

Roedd hi wedi dysgu amall, bod yn barod a bod yn gallu gyrru awyrgylch ei hun.

She had learned to be ready and be able to drive her own atmosphere.

Roedd hi'n gweld nad oedd angen cynllunio popeth, ac weithiau yw ffordd arall ar gyfer y daith sydd i ddod.

She realized that not everything needed to be planned, and sometimes another way was the journey to come.

Roedd newid, fel eira annisgwyl, weithiau'n bleser annisgwyl.

Change, like unexpected snow, was sometimes an unexpected delight.
