Yn nghanol y parc cenedlaethol Eryri, lle mae natur a'r hud yn cwrdd, roedd glanfa gudd wedi ei hamgylchynu gan lliwiau amrywiol yr hydref.

In the middle of the Parc Cenedlaethol Eryri, where nature and magic meet, there was a hidden landing surrounded by the varied colors of autumn.

Mae'r awyr yn llwyd golau, ac mae awel oer yn dod ag addewid o'r gaeaf.

The sky was a light gray, and a cold breeze brought a promise of winter.

Roedd Gwilym, botanegydd penderfynol mewn chwilio am ffrwyth ei lafur, wedi clywed sïon am flodyn prin a blodeuai unwaith yn unig ym mis Tachwedd.

Gwilym, a determined botanist seeking the fruit of his labor, had heard rumors of a rare flower that would bloom only once in November.

Mae hyn yn ei symbylu i ymgymryd â’r daith hon, gyda Mared, ei ffrind plentyndod gafaelgar, a’i chwaer Eirwen dawel ond cefnogol yn ei gwmni.

This inspired him to undertake this journey, accompanied by Mared, his tenacious childhood friend, and his quiet but supportive sister Eirwen.

Wrth i'r tri lywio trwy'r coed trwchus, roedd Gwilym yn llawn brwdfrydedd.

As the three of them navigated through the dense woods, Gwilym was full of enthusiasm.

Roedd yn dyheu am ddod o hyd i'r blodyn, a oedd yn cael ei ystyried yn gwyrthiol ac yn aros i fod yn gyflawniad mawreddog yn y gymuned fatanaidd.

He was eager to find the flower, which was considered miraculous and awaited to be a great achievement in the botanic community.

Yn ei galon, roedd yn gweld tocynnau glod iddo ef ei hun.

In his heart, he envisioned tokens of praise for himself.

Ar yr un pryd, roedd Mared wrth ei bodd gyda'r antur a'r digonedd o ddiweddglo posibl.

At the same time, Mared was thrilled with the adventure and the abundance of possible outcomes.

Ond roedd Eirwen yn cysgodu pryder am adfeiliedig natur y dietifibran.

But Eirwen harbored concerns about the transient nature of the endeavor.

Roedd hi’n ei gweld hi’n lleddf i’r gwir y gallai bygythiad o ddinistr newid popeth.

She found it hard to accept the truth that the threat of destruction could change everything.

Roedd hi’n ofni, pe bai’r blodyn yn dod yn hysbys, y byddai ei ddiogelwch yn cael ei beryglu.

She feared that if the flower became known, its safety would be jeopardized.

Roedd yn ei arosg am ei chlodfawrogiad ei hun dros diffyg meddylgarwch Gwilym.

She awaited her own appreciation over Gwilym's thoughtlessness.

Trwy'r dirgelwch ir, arhosodd y griw amrywiol i'r glanfa hudol, a dyna lle gwelsant y blodyn.

Through the lush mystery, the diverse group reached the magical landing, and there they saw the flower.

Ar ochr y bont mân, roedd yn llathred lluosflawn golwg.

Beside the slender bridge, it gleamed with a multitude of vibrant hues.

Mewn eiliad o dawelwch sanctaidd, roedd stondin naturiol Gwilym yn ymgynnull o flaen y blodyn.

In a moment of sacred silence, Gwilym's natural stature gathered before the flower.

Fodd bynnag, cyn i Gwilym wasgu'r sbesimen prin, dechreuodd y gwyntau gyflymu fel rhu barn.

However, before Gwilym could press the rare specimen, the winds began to speed up, like the roar of judgment.

Daeth oerfel ystorm hydref tua hwynt yn sydyn, gan eilio oera'r aer ac aros am yr hyn a'mrws i ddod.

The cold of an autumn storm came upon them suddenly, chilling the air and waiting for the inevitable to unfold.

Yn y fan honno, edrychodd Gwilym i lygad Eirwen.

In that instant, Gwilym looked into Eirwen's eyes.

Gwelodd yn ei golwg Gymraeg plaen, gwerth mwy: natur lawn ein tystiolaeth.

He saw in her plain Cymraeg expression, a greater truth: a full understanding of our witness to nature.

Heb uniaethu na siarad mwy, deallodd y diffyg trechwng a rhaid iddo adael y blodyn yn ddiarwybod a diogelu.

Without identifying or speaking further, he understood the lack of victory and knew he must leave the flower untouched and safeguard it.

Nodwedd garu Eirwen ar gyfer surio'r hirfelyn sy'n ei leoli.

Eirwen's loving nature guided the remorseful brother to his revelation.

Eiriodd y storm, a chafodd y trio'r her o ddychwelyd gartref.

The storm subsided, and the trio faced the challenge of returning home.

Wrth iddynt gyfeirio'n araf tuag adre, arhosodd cysylltiad newydd rhwng y chwaer a’r brawd haeriol yma’i bod.

As they slowly headed back, a new connection formed between sister and defiant brother.

Wedi i’r tywydd cuddio allan, gwybodaeth weithredol y pedol roedd arwyddocâd newydd o rwystro iddynt.

Once the weather cleared, there was an operational awareness of the horseshoe's new significance to them.

Gwelai Gwilym yn awron, ba oedd i ddysgu, bod rhai pethau'n haul yn eu hoes ymroi—yn well ar gyflawniad unigol na chlod.

Gwilym now saw, what was to be learned, that some things shine in their self-sacrifice—better as personal achievement than praise.

Yn y diwedd, roedd y blodyn yna o hyd, ar ddiethriad, a ddyfynner dan loches, a’r cariad ffyrnig i’w waed.

In the end, the flower remained there, undisturbed, under its shelter, with fierce love in its veins.
