Roedd haul yr haf yn gwynto dros y dref fach.

The summer sun was casting its warmth over the little town.

Roedd pawb yn dathlu Diwrnod Bastille dros y môr, ond roedd Eira, gyda'i chwilfrydedd naturiol, yn cerdded tuag at hen warys.

Everyone was celebrating Diwrnod Bastille across the sea, but Eira, with her natural curiosity, was walking towards the old warehouse.

Roedd hon wedi bod yn lle dirgel ers tro, wedi'i adael gyda ffenestri torri a metel rhydlyd.

This place had been a secret for a long time, abandoned with broken windows and rusty metal.

Torrwyd y tawelwch y tu mewn yn unig gan gamau troed Eira.

The silence inside was broken only by Eira's footsteps.

Wrth fynd ar hyd llwybr o bridd a gwymon wedi gordyfu, gwelodd Eira olion traed.

As she walked along a path of overgrown soil and seaweed, Eira noticed footprints.

Roedd y rhain yn arwain i mewn i hen ddeorfa, gan wthio ei chwilfrydedd.

These led into an old hatchery, pushing her curiosity further.

Penderfynodd Eira ddilyn y traed hyn.

Eira decided to follow these footprints.

Roedd cyffro a gofid yn gwneud cymysgedd od yn ei chalon.

A mix of excitement and worry formed a strange blend in her heart.

Ddilynodd Eira y traed i mewn, a darganfu'r llawr yn ansad a'r cornelau wedi'u cuddio yn llethol.

Eira followed the footprints inside, discovering the floor was unstable and the hidden corners were overwhelming.

Roedd Gwyn a Tegan, ffrindiau Eira, wedi rhybuddio am berygl y fan hon.

Gwyn and Tegan, Eira's friends, had warned her about the dangers of this place.

Ond, roedd rhaid i Eira wynebu'b ofnau hyn i ddatrys y dirgelwch.

But, Eira had to face these fears to solve the mystery.

Roedd hi'n twyru drwy'r cysgodion, ac yn y diwedd, daeth hi at ystafell gudd.

She was feeling her way through the shadows, and eventually, she came to a hidden room.

Roedd cliwiau ar draws y waliau, yn awgrymu bod y warys yn fan cyfarfod i grŵp cyfrinach.

Clues were spread across the walls, suggesting the warehouse was a meeting place for a secret group.

Roedd y traed wedi bod gan rywun arall, rhywun hefyd yn ceisio datgelu'r stori gudd.

The footprints belonged to someone else, someone also trying to reveal the hidden story.

Cyn gynted ag y daeth hi â chlust yn erbyn drysau'r ystafell, cafodd clywedon.

As soon as she put her ear against the doors of the room, she overheard voices.

Peidiodd hi, ond dim cyn codi dyddiadur dirgel yn llawn o adroddiadau cryptig.

She paused, but not before picking up a mysterious diary full of cryptic reports.

Wedi'i bompio â chyfeillgarwch gudd ei chalon, dihangodd Eira o'r warys gyda'r dyddiadur yng nghlorhau.

With her heart buoyed by the secretive camaraderie, Eira escaped from the warehouse with the diary in her grasp.

Nawr, synnai'r pos i dadlwytho stori'r hen warys.

Now, she was intrigued to unravel the story of the old warehouse.

Gan ddianc yn ddiogel gyda thystiolaeth newydd a llawn hyder newydd yn ei sgiliau ditectif, teimlai Eira wedi'i yrru.

Escaping safely with new evidence and a newfound confidence in her detective skills, Eira felt driven.

Roedd lleisiau'r gorffennol a'r dirgelwch yn sôn wrth iddi gerdded yn ôl i'r golau haul, yn barod i ddatgelu straeon colledig yr hanes.

The voices of the past and the mystery spoke to her as she walked back into the sunlight, ready to reveal the lost stories of history.
