Wrth i dail cochaidd yr Hydref chwythu heibio'r ffenestri mawr, roedd yr awyrgylch yn swyddfa'r corfforaeth yn drylwyn.

As the crimson leaves of Autumn blew past the large windows, the atmosphere in the corporation's office was tense.

Roedd Eira yn eistedd wrth ei desg gyda pen dynn, yn trio canolbwyntio.

Eira sat at her desk, with a tight expression, trying to concentrate.

Roedd problem fawr yn ei hwynebu - dogfennau pwysig wedi diflannu.

A major problem faced her - important documents had gone missing.

Roedd y cyfarfod mawr i fod i ddechrau mewn llai na hanner awr.

The major meeting was supposed to start in less than half an hour.

Roedd y swyddfa’n llawn bocsiau symud a llwch o'r gwaith ailwampio diweddar.

The office was full of moving boxes and dust from the recent renovations.

Roedd yn fyd o anhrefn, a hyd yn oed gyda'i threfnusrwydd arferol, teimlai Eira yn orbryderus.

It was a world of chaos, and even with her usual organization, Eira felt anxious.

Wrth i'r haul Hydrefol llusern golau o liw aur trwy'r paneli gwydr, roedd angen help arni.

As the Autumn sun cast a golden light through the glass panels, she needed help.

Gwnaeth Eira ei ffordd at ddesg Gwyn.

Eira made her way to Gwyn's desk.

Roedd Gwyn yn hamddenol fel arfer, yn poryw ar yr un stori ar-lein, chwerthin ar ei ffôn.

Gwyn was as relaxed as ever, browsing the same online story, laughing at his phone.

Roedd yn arferiad syml i'r swyddfa feddwl mai'r dyn aven ar Gundlwyn yn ofalus ydoedd, ac roedd hynny'n cythruddo Eira.

It was a simple habit in the office to think of him as the careful "aven man on Gundlwyn," and that irritated Eira.

Eto, roedd arni angen cymorth.

Yet, she needed help.

"Efallai gallet ti fy helpu i?

"Perhaps you could help me?"

" gofynnodd Eira, gydag ychydig o ansicrwydd yn ei llais.

asked Eira, with a bit of uncertainty in her voice.

"Wrth gwrs, Eira," medd Gwyn, gan roi'r ffôn i lawr.

"Of course, Eira," replied Gwyn, putting the phone down.

"Beth yw'r cliw cyntaf?

"What's the first clue?

Fe allwn ni ddod o hyd iddynt os ydyn ni’n meddwl tu allan i'r bocs.

We can find them if we think outside the box."

" Roedden nhw'n chwilio trwy ffeiliau a phapurau ar draws y swyddfa, roedd yr amser yn ticio.

They searched through files and papers across the office, time ticking away.

Eira'n teimlo'r pwysau'n cryfder cyferbyn â sêr y dydd.

Eira felt the pressure mounting compared to the day's stars.

Roedd y llythyrwon a'r ffeiliau yn edrych i gyd fel un peth mawr.

The letters and files all seemed like one big mess.

Ond, roedd Gwyn yn dal i'w hamser i feddwl tuag at y cerrig mân cudd a oedd wedi eu lleoli bron ar ochr y swbstradau symud.

However, Gwyn took his time to think about the hidden pebbles located nearly at the edge of the moving substrates.

"Hei," medd Gwyn, wrth iddo fynd tuag at un o'r pentyrrau o gyflenwadau adeiladu.

"Hey," said Gwyn, as he went toward one of the piles of building supplies.

"Beth am edrych yma?

"How about we look here?"

"Wrth ofalu symud rhyw reiad a bwrdd llawn amlap a ffolderau, gwelodd Eira y ffolder glas.

Carefully moving some kind of wainscoting and a table full of envelopes and folders, Eira saw the blue folder.

"Ti dod i wneud?

"You found it?"

" roedd Gwyn yn wên.

Gwyn was smiling.

Roedd ei gwythiennau yn pwyso, eto roedd y lliniaru yn y newydd hwn.

Her veins were pulsing, yet there was relief in this news.

"Diolch, Gwyn," dywedodd Eira.

"Thank you, Gwyn," said Eira.

Wedi ichi symud pob thoe ac atodiad i'w lle, cyrhaeddodd yr ystafell gyfarfod ynghynt nag roeddent yn disgwyl.

After moving every attachment and document into place, they arrived at the meeting room sooner than expected.

Roedd Eira'n disgleirio o ddiweddglo iechyd.

Eira was glowing with a sense of healthy completion.

Yn ystod y cyfarfod, trafodwyd dogfennau'r prosiect heb gymhedru.

During the meeting, the project documents were discussed seamlessly.

Wrth i'w chydweithwyr ddatgan eu hedmygedd at ei threfnusrwydd, roedd Gwyn yn derbyn clod am ei graffter.

As her colleagues expressed admiration for her organization, Gwyn was praised for his insight.

Teimlai Eira ddiolchgar iawn.

Eira felt very grateful.

Roedd ei golwg wedi newid - gwaith tîm oedd hwn.

Her outlook had changed - this was teamwork.

Dysgodd Eira bod cydweithio yn dod â gwerth a chreadigrwydd.

Eira learned that collaboration brings value and creativity.

Fe wnaeth hefyd newid y ffordd roedd yn gweld Gwyn.

She also changed the way she saw Gwyn.

O fath newydd oedd y dyn, y llen iddo gael ei godi.

He was of a new kind, the veil lifted from him.

Roedd arni'i golygu trius pâl y dyfodol i raddedigion, gyda datganiadau'n cael eu gwefru a'r cloegwent yn parhau.

She set about planning a bright future for the graduates, with declarations being charged and the mystery continuing.

Roedd y swyddfa'n edrych fel maes rhyfedd ond roedd y gwir ymgyrchu yn ddidwyll.

The office looked like a strange field, but the real campaign was sincere.

Roedd mewn gwirionedd newydd ddechrau.

It had, in fact, just begun.
