Roedd y noson yn cyrraedd ar gafael ar gymuned gâtiedig Caerdydd.

The night was taking hold over Cardiff's gated community.

Roedd y strydoedd yn llawn o dynnu cnau, a'r tai wedi'w haddurno'n brydferth gyda phwmpenni a gweoedd pry cop i ddathlu Calan Gaeaf.

The streets were full of trick-or-treaters, and the houses beautifully decorated with pumpkins and cobwebs to celebrate Halloween.

Roedd ysgol y gymuned, yn brysur yn paratoi ar gyfer sioe dalent a fyddai'n digwydd y noson honno.

The community school was busy preparing for a talent show that would take place that night.

Ymhlith y mwyaf cyffrous i gymryd rhan oedd bachgen tawel o'r enw Gareth.

Among the most excited to participate was a quiet boy named Gareth.

Roedd Gareth yn ddeuddeg oed ac yn caru chwarae'r gitâr.

Gareth was twelve years old and loved playing the guitar.

Yn ddwfn mewn ei galon, roedd eisiau dangos ei hunan.

Deep in his heart, he wanted to show himself.

Roedd yn breuddwydio am sefyll ar lwyfan y sioe dalent.

He dreamed of standing on the talent show stage.

Er hynny, roedd ofn yn rheoli ei feddwl.

However, fear ruled his mind.

Meddyliau am farn ei gyfoedion oedd yn ei ddal yn ôl.

Thoughts of his peers' judgment held him back.

Roedd yn gwybod na allai lwyddo heb gefnogaeth.

He knew he couldn't succeed without support.

Gwnaeth Gareth benderfyniad anodd ond dewr: roedd yn mynd i arwyddo ei enw i'r sioe.

Gareth made a difficult but brave decision: he was going to sign his name for the show.

Adeiniodd ei hunain dros ben y byrfyfyr drwy addurno ei iard gefn gn' hardd i groesawu ei gymdogion, Rhys a Carys.

He amused himself by decorating his rear yard beautifully to welcome his neighbors, Rhys and Carys.

Pan welodd Rhys a Carys addurniadau Gareth, roeddent wedi'u synnu.

When Rhys and Carys saw Gareth's decorations, they were surprised.

Dechreuon nhw siarad â Gareth, ac yn fuan, fe ddaethon nhw'n gyfeillion.

They started talking to Gareth, and soon, they became friends.

Anogodd Rhys ac Carys Gareth i wneud y gorau o'i ofnau.

Rhys and Carys encouraged Gareth to make the most of his fears.

Gyrhaeddodd diwrnod y sioe dalent, a'r ysgol yn gynnes â'r awyrgylch gyffrous.

The day of the talent show arrived, and the school was warm with an exciting atmosphere.

Roedd tai'r plant wedi'u trawsnewid i wynebau cynhyrfus.

The children's faces had been transformed into eager expressions.

Pan gyhoeddwyd enw Gareth i fyny ar y llwyfan, roedd ofn yn amgylchynu ei galon yn dynn.

When Gareth's name was announced on stage, fear tightened around his heart.

Yn y fan honno, cododd Rhys a Carys eu dwylo o'r dorf, eu taweliaeth a'u gwên yn cynnig cyffordd.

At that moment, Rhys and Carys raised their hands from the crowd, their calmness and smile offering comfort.

Roedd yn llawn cysur i Gareth.

It was a source of immense comfort to Gareth.

Trodd i wynebu'r dorf, a dechrau chwarae ei gitâr.

He turned to face the crowd and began playing his guitar.

Roedd yn gwadu'n hawdd, gyda'i ddwylo'n symud yn rhwydd dros y tannau.

He played effortlessly, his hands moving smoothly over the strings.

Torrodd distaw'r ystafell â seiniau'r gitâr hudolus, a llyncodd pawb airrodd o harddwch ei ddanteithion.

The room's silence was broken by the magical sounds of the guitar, and everyone was captivated by the beauty of his melodies.

Ar ddiwedd y perfformiad, cochodd Gareth mewn llawenydd pan nad oedd cefnogwyr yn aros rhag clapio.

At the end of the performance, Gareth blushed with joy as supporters didn't stop clapping.

Roedd Rhys a Carys wrth ei ochr, eu llygaid yn llawn rhyfeddod a balchder.

Rhys and Carys were beside him, their eyes full of wonder and pride.

Ar yr eiliad honno, sylweddolodd Gareth, drwy drechu'i ofnau, yr oedd wedi ennill mwy na dim ond llwyddiant; roedd wedi ennill ffrindiau, derbyniad a hyder.

In that moment, Gareth realized that by conquering his fears, he had gained more than just success; he had gained friends, acceptance, and confidence.

Roedd y byd nawr yn llai llwm ac ofnus iddo.

The world now seemed less bleak and frightening to him.

Roedd y nos, er ei natur oer ac ofnadwy, wedi dod â gwyddwn newydd o gynhesrwydd a chyfeillgarwch, yn enwedig yn y gymuned gâtiedig lle oedd Gareth yn cartrefu.

The night, despite its cold and spooky nature, had brought a new kind of warmth and friendship, especially in the gated community where Gareth resided.
