Ar ddiwedd haf heulog, roedd teulu Emrys a Gwyneth yn ymgasglu wrth lannau Llyn Efyrnwy.

At the end of a sunny summer, Emrys and Gwyneth's family gathered by the shores of Lake Vyrnwy.

Roedd aduniad y teulu yn gyfle i bawb ddod at ei gilydd, ond eleni, roedd rhywbeth yn wahanol.

The family reunion was an opportunity for everyone to come together, but this year, something was different.

Roedd yr heirloom teuluol enwog ar goll, ac roedd tensiwn yn crwydro drwy'r aer fel cwmwl du dros y môr tawel.

The famous family heirloom was missing, and tension drifted through the air like a dark cloud over the calm sea.

Emrys, sefyll ar wahân o'r criw, yn syllu ar y dŵr glesni.

Emrys, standing apart from the group, stared at the blue waters.

Am flynyddoedd, roedd yn teimlo'n allanol yn y teulu.

For years, he felt like an outsider in the family.

Ond gyda'r heirloom ar goll, roedd cyfle o'r diwedd iddo brofi ei hun.

But with the heirloom missing, there was finally a chance for him to prove himself.

Yn rowndau'r coelcerthi, roedd gwyngalchu cyhuddiadau a darnau drwg-weld o wybodaeth.

Among the rounds of bonfires, exchanged accusations and poorly-seen snippets of information were shared.

"Emrys," meddai llais tawel wrth ei ochr.

"Emrys," said a quiet voice beside him.

Gwyneth oedd yno, ei llygaid yn llawn chwilfrydedd.

It was Gwyneth, her eyes full of curiosity.

"Lleogdydd ti am help?

"Would you like some help?"

"Ystyriodd Emrys hyn am eiliad.

Emrys considered this for a moment.

Roedd hi'n frawychus agor ei hun, ond er yn amheus, roedd yn gwybod na allai wneud hyn ar ei ben ei hun.

It was daunting to open himself up, but despite his doubts, he knew he couldn't do this alone.

"Byddai'n werthfawr i mi, Gwyneth," atebodd, diweddglo o ddewrder yn ei lais.

"It would be valuable to me, Gwyneth," he replied, a hint of courage in his voice.

Dechreuwyd y chwiliad gyda gofal, gan ddilyn marciau hen y teulu.

The search began carefully, following the worn marks of family history.

Roeddant yn treiddio'n ddwfn i goeden hanesion, gan ddod ar draws llythyr wedi'i guddio yn y pren sy'n dweud am gyfrinachau'r gorffennol.

They delved deep into the tree of histories, uncovering a letter hidden in the wood that spoke of past secrets.

Digon i roi cracyll ar unrhyw un, ond nid iddynt.

Enough to startle anyone, but not them.

Wrth bersheithio hen lythyr, darganfuwyd gwir leoliad yr heirloom – mewn ogof yn y mynyddoedd.

Through deciphering the old letter, they discovered the true location of the heirloom—in a cave in the mountains.

Yno, rhwng crugecosau llachar, roedd môr o ddystysgog anfarwol, a than wyliad athro a chwilio dwfn, camodd Emrys i gwblhau'r dasg.

There, among bright stalactites, lay a sea of timeless wisdom, and under the watchful eye of their pursuit, Emrys stepped in to complete the task.

Pan ddaeth y ddau yn ôl i'r hafod, roedd y teulu'n llanast, ond roedd yr heirloom yn ddarpar ac yn haraith.

When the two returned to the cottage, the family was in disarray, but the heirloom was restored and intact.

Roedd yn ddigon i gynhesu'r calonnau a thawelu'r stŵr.

It was enough to warm their hearts and quell the commotion.

Emrys sicrheid nawr y camodd tuag at y teulu fel rhan ohonynt, nid yn unig fel yhongan.

Emrys now knew that he had stepped towards the family as a part of them, not just as an individual.

Trodd Gwyneth at Emrys gyda wên hyfryd.

Gwyneth turned to Emrys with a lovely smile.

"Beth yw'r traddodiadau os nad ydyn nhw'n ein helpu?

"What are traditions if they don't help us?"

" meddai yn ddoeth, gan ddangos ei phlannu'n gadarn yng nghalon traddodiadau pellach ond meddwl agored.

she said wisely, showing her firm roots in far-reaching traditions but open-minded thinking.

Gyda'r heirloom yn aros yn llonydd, roedd y teulu'n gweld y posibiliadau o uno ar sail gwirionedd, nid traddodiad methiant.

With the heirloom resting quietly, the family saw the possibilities of uniting based on truth, not failed tradition.

Roedd Llyn Efyrnwy yn brydferth fel erioed.

Lake Vyrnwy was as beautiful as ever.

Ond rhyw sut, gwyddai'r teulu y byddai'n darparu atgofion heddychlon, nid tensiynau troellog, ar gyfer aduniad y flwyddyn nesaf.

But somehow, the family knew it would provide peaceful memories, not swirling tensions, for next year's reunion.
