Roedd haf yn y coedwig gudd, lle'r oedd y dail gwyrddlas yn dechrau sibrwd gyda'r gwynt ysgafn.

It was summer in the hidden forest, where the greenish-blue leaves began to whisper with the gentle wind.

Yn ganol y coedwig, dyma lechi Emlyn y labordy cyfrinachol.

In the middle of the forest, Emlyn's secret laboratory was located.

Roedd ei daid, gwyddonwr ecsentrig, wedi adeiladu hwn flynyddoedd yn ôl, yn llawn peiriannau hen ffasiwn a dyfeisiadau rhyfedd.

His grandfather, an eccentric scientist, had built it years ago, filled with old-fashioned machines and strange inventions.

Amledd y peiriannau yn asio â swyn y coed.

The hum of the machines blended with the enchantment of the trees.

Roedd Emlyn ar genhadaeth beryglus: darganfod fformwla cryptig a allai newid cwrs esblygiad dynol.

Emlyn was on a dangerous mission: to discover a cryptic formula that could change the course of human evolution.

Roedd y fformwla hon wedi ei cuddio’n ofalus gan ei daid, y dyn dieithr a wyddai gormod am y dyfodol.

This formula had been carefully hidden by his grandfather, the stranger who knew too much about the future.

Ond nid oedd Emlyn ar ei ben ei hun; roedd Carys a Gwyn, ei gyd-ymchwilwyr, wrth ei ochr.

But Emlyn was not alone; Carys and Gwyn, his fellow researchers, were by his side.

Roedd rhaid iddo ddibynnu arnynt, er bod y risg o frad bob amser yn cael ei hystyried.

He had to rely on them, even though the risk of betrayal was always considered.

Wrth iddynt fynd i mewn i'r labordy, roedd yr ystafelloedd yn dywyll a’r awyr yn llawn esmwyth o lyfrau lliw a phapurau.

As they entered the laboratory, the rooms were dark and the air filled smoothly with colorful books and papers.

Roedd peiriannau anhygoel yma ac acw, yn gwylltio gyda'r fedrusrwydd o'i daid.

There were incredible machines here and there, crafted with his grandfather's skill.

Ond roedd y llwybrau yn dan warchodaeth riddfeydd a systemau diogelwch cymhleth.

But the paths were under the protection of riddles and complex security systems.

Daeth y grŵp a lwyddo drwy'r problemau hynny, gan ddefnyddio gwybodaeth a chyfeillgarwch i ddatrys pob cyfrinach.

The group succeeded in overcoming those challenges, using knowledge and friendship to solve every mystery.

Ar y diwedd, roeddem yn sefyll o flaen y siambr olaf.

In the end, they stood before the final chamber.

Wrth edrych ar y drws mawr, arhosai Emlyn am eiliad.

Looking at the large door, Emlyn paused for a moment.

Roedd hwn yn foment tyngedfennol.

This was a crucial moment.

Pe bai'n cadw'r fformwla, gallai wneud enw i'w hunan a gadael enwogrwydd gwyddonol.

If he kept the formula, he could make a name for himself and achieve scientific fame.

Ond beth pe bai'r pŵer hwn yn syrthio i'r dwylo anghywir?

But what if this power fell into the wrong hands?

Gydag ysbrydiaeth sydyn, difethaodd Emlyn y fformwla.

With sudden inspiration, Emlyn destroyed the formula.

Deallai nad oedd enw da nac arian yn werth perygl cynhenid y fformwla.

He understood that reputation and money were not worth the inherent danger of the formula.

Trwy wneud hynny, rhyddhaodd gweddill y labordy, gan ddangos parch tuag at holl gyflawniadau arbennig ei hen daid.

By doing so, he liberated the rest of the laboratory, demonstrating respect towards all the extraordinary achievements of his late grandfather.

Mae Emlyn bellach yn gwyddonwr aeddfed, gyda mwy o werth ynglŷn â moeseg a chyfrifoldeb.

Emlyn is now a mature scientist, valuing ethics and responsibility.

Mae wedi dysgu bod pŵer yn galw am gyfrifoldeb mawr, ac o'r coedwig breuddwydiol hynny, mae'n marchio ymlaen, yn fwy doeth a chyfiawn nag erioed o’r blaen.

He has learned that power calls for great responsibility, and from those dreamlike woods, he marches forward, wiser and more just than ever before.
