Gareth, Carys, a Rhys oedd yn sefyll y tu allan i warys gwag ger Bae Caerdydd.

Gareth, Carys, and Rhys were standing outside an empty warehouse near Cardiff Bay.

Roedd awel hydref yn chwythu drwy'r coed, gan ddwyn dail coch a melyn ar hyd y llawr.

An autumn breeze was blowing through the trees, carrying red and yellow leaves across the ground.

Roedd y prosiect ysgol am archwilio trefol yn gyfle i gynnig rhywbeth unigryw a phwerus, a Gareth eisiau argraffu Carys gyda'i waith.

The school project about urban exploration was an opportunity to offer something unique and powerful, and Gareth wanted to impress Carys with his efforts.

"Mae'n edrych yn ddiogel," meddai Carys yn gyffrous, ei llygaid yn disgleirio.

"It looks safe," said Carys excitedly, her eyes gleaming.

Rhys, ar y llaw arall, edrychodd yn amheus.

Rhys, on the other hand, looked skeptical.

"Mae'n bert, ond dw i ddim yn siŵr a ydy hyn yn syniad da."

"It's pretty, but I'm not sure if this is a good idea."

Gareth 'i ddigon tew drefnau, rhaidi đánh tua glayrs–- roedd ganddo restr o bopeth y dylai ei wneud, ond roedd Carys yn ei denu i ymdrochi mewn antur.

Gareth was quite enthusiastic about planning, eager to tackle this challenge with a determined spirit—he had a list of everything he should do, but Carys was tempting him to plunge into adventure.

“Gadewch i ni fynd i mewn,” meddai Carys, gan ddechrau cerdded tuag at ddrws mawr y warys.

“Let's go inside,” said Carys, starting to walk towards the large door of the warehouse.

Edrychodd Gareth ar Rhys, sy’n siarad trwy ffrintiau clen.

Gareth looked at Rhys, who spoke in a friendly manner.

“Jyst ddylso ni bod yn ofalus, Gareth,” cynghorodd Rhys, ond roedd Carys eisoes wedi diflannu tu fewn.

“We just need to be careful, Gareth,” advised Rhys, but Carys had already disappeared inside.

Unwaith i mewn, roedd y tŷ mawr yn llawn atseiniau’r gorffennol diwydiannol.

Once inside, the large house was filled with echoes of its industrial past.

Roedd golau truenus yn treiddio drwy’r ffenestri gwag, a sŵn y dail yn crensian dan draed Carys wrth iddi gerdded o gwmpas.

A pitiful light filtered through the empty windows, and the sound of leaves crunching under Carys' feet echoed as she walked around.

Yna, digwyddodd rhywbeth.

Then, something happened.

Roedd llawr y ddau ystafell uwchlaw’n dechrau crymu yn danffordd.

The floor of the two rooms above began to bend ominously.

Cawsant clywed y sŵn rhyfedd o’r agosau.

They could hear a strange noise approaching.

“Cadwch nôl!” galwodd Rhys, gan dynnu Gareth yn ôl gyda'i ddwylo.

“Stay back!” called Rhys, pulling Gareth back with his hands.

Roedd Gareth yn gweld Carys yn sefyll yn ynysig, y ddaear yn crynu, yng nghanol y llawr.

Gareth saw Carys standing isolated, the ground trembling beneath her, in the middle of the floor.

Roedd rhaid iddo weithredu.

He had to act.

Heb feddwl, torchiodd Gareth drosodd i lawnt tuag at Carys.

Without thinking, Gareth dashed across the lawn towards Carys.

“Mae'n rhaid i ni symud, nawr!” gwaeddodd, ei galon yn rasio.

“We need to move, now!” he shouted, his heart racing.

Dringodd gyda’i gilydd, Gareth yn arwain y ffordd, a'u hatgoffa bod angen bod yn gyflym ond yn ofalus.

They climbed together, Gareth leading the way, reminding them to be quick but careful.

Wrth iddynt ddefnyddio'r diro hwn hen un esch prifeiddau, gorffennodd y rhwystr heblaw am eu laaabau.

As they navigated through this old space, they overcame each obstacle.

Mae Gareth gafaeliad y sefyllfa mewn union amser, ac ymadawodd y grŵp o’r warys yn ddiogel.

Gareth grasped the situation just in time, and the group exited the warehouse safely.

Wrth iddynt sefyll y tu allan, dim ond sŵn y dail yn crensian am gain y dydd yn cgerdd ymlaen.

As they stood outside, only the sound of leaves crunching underfoot accompanied the continuing day.

"Diolch, Gareth," meddai Carys, ei lygabi nedg ar ei fry rygd y tynnu gwresag.

"Thank you, Gareth," Carys said, her eyes shining as she smiled at him.

Roedd Gareth yn teimlo sgiliau o gysylltiad.

Gareth felt a sense of connection.

Mae Rhys yn chwerthin, yn taflu i lawr, ond yn syth ddigon ffrind.

Rhys laughed, patting Gareth on the back, a genuine friend.

"Wel, mae'n edrych fel bod y goleuo'n i nôl, yn y cyd-fodd."

"Well, it looks like we're back, all in good spirits."

Roedd Gareth wedi dysgu gwers bwysig.

Gareth had learned an important lesson.

Difyr uwch gyfyngiadau parch i'r rhaglen.

It was amusing beyond respect for the program's constraints.

Roedd yn teimlo'n falch oherwydd ei bod wedi darganfod cydbwysedd newydd rhwng bod yn ofalus ac ant, ac roedd cydnabod y ddau yn ihadore.

He felt proud because he had discovered a new balance between being cautious and adventurous, acknowledging both as valuable.

Roedd rhodd achub rhywbeth unig an o rhythm gwahanol, a Gwynnydd yn llicha ar yr achyfrifiant ohono.

There was something unique about the rhythm of rescuing, and the journey left its mark on him.
