Story Transcript:

Cy: Yng nghanol y gwanwyn, o dan planhigion gwyrddlas a blodau newydd ar wynt y mynyddoedd, stori dywyll oedd yn datblygu dan y ddaear.
En: In the middle of spring, under greenish plants and new flowers on the mountain winds, a dark story was unfolding underground.

Cy: Yn y cymoedd agos at y pwll glo segur, roedd dirgelwch yn symud gyda chyfres o ysgytiadau anghyffredin.
En: In the valleys near the idle coal pit, a mystery was moving with a series of unusual tremors.

Cy: Roedd Gethin, brwd hanesydd lleol, yn teimlo'r adrannau hanes heb eu darganfod yn galw ato.
En: Gethin, an enthusiastic local historian, felt the undiscovered chapters of history calling to him.

Cy: "Beth yw'r dirgelwch yma?
En: "What is this mystery?"

Cy: " meddai Gethin.
En: said Gethin.

Cy: "Mae angen i ni wybod.
En: "We need to know."

Cy: " Roedd ganddo ddamcaniaeth y gallai arteffactau cudd bodoli yn y dulliai islaw, ac efallai mai rhywbeth oedd yn achosi'r ysgytiadau.
En: He had a theory that hidden artifacts might exist in the tunnels below, and perhaps something was causing the tremors.

Cy: Gyda Rhian, daearegwr profiadol, a Tegan, newyddiadurwraig ddiddraig, fe ddechreuon nhw ymchwilio.
En: With Rhian, an experienced geologist, and Tegan, a curious journalist, they began investigating.

Cy: Rhian, â'i gwybodaeth fanwl o ddaeareg, oedd yn poeni am y posibilrwydd o dirlithriad peryglus.
En: Rhian, with her detailed knowledge of geology, was worried about the possibility of a dangerous landslide.

Cy: Ond roedd Tegan, yn anesmwyth am wirionedd dirgel a fyddai’n hwb mawr i'w gyrfa.
En: But Tegan, anxious for a mysterious truth that would be a major boost to her career.

Cy: Roedd gan bob un agenda eu hunain.
En: Each had their own agenda.

Cy: Panethodd yr haul trwy'r cwm, a Gethin oedd yn gyntaf i sylweddoli'r glud ar y muriau garw o wyneb carreg y pwll.
En: The sun glinted through the valley, and Gethin was the first to notice the gleam on the rough walls of the pit's stone face.

Cy: Roedd hynny'n dangos iddo fod tir tueddiadol o symud.
En: It showed him that the ground was prone to movement.

Cy: "Beth os ydi'r cysgodion hyn yn cuddio cyfrinach?
En: "What if these shadows hide a secret?"

Cy: " Golygon cyflym a ddangosodd dadansoddiad Rhian ei bod hi'n bosibl oedd hynny.
En: A quick analysis by Rhian showed it was possible.

Cy: Ar yr un pryd, roedd Tegan yn ystyried ei chweithiau.
En: At the same time, Tegan was considering her options.

Cy: Wrth iddyn nhw wibio lawr i gynteddau tywyll y pwll, gyda'i gynheiliadau pren a'r golau torllwys bob cam, cawsant eu syfrdanu gan ysgytwad sydyn.
En: As they hurried down into the dark corridors of the pit, with its wooden supports and dim light every step of the way, they were startled by a sudden jolt.

Cy: Roedd hynny'n ddigon i wneud i'w calonau ddal eu gwynt.
En: It was enough to take their breath away.

Cy: Ond yr oedd yn blys hefyd, o beidio rhoi'r gorau.
En: But there was also a desire not to give up.

Cy: Ar y foment gywir, ymddangosodd agoriad i siambr gudd.
En: At the right moment, an opening to a hidden chamber appeared.

Cy: "Dyma hi!
En: "There it is!"

Cy: " gwaeddodd Gethin, wrth sylwi ar arteffactau o arwyddocâd hanesyddol.
En: shouted Gethin, upon noticing artifacts of historical significance.

Cy: Dechreuon nhw sesiwn na darllen dim byd yn y llyfrau hanes.
En: They began a session neither of them had read about in history books.

Cy: Ond, yn sydyn, cafwyd tremor arall.
En: Suddenly, there was another tremor.

Cy: Roedd Rhian yn beirniadu eu hanghymryd o beidio sylwi ar beryglon.
En: Rhian criticized their neglect in not noticing the dangers.

Cy: "Rhaid i ni fynd," ymyrryd Rhian mewn brysiad.
En: "We must go," intervened Rhian hastily.

Cy: Ond roedd Gethin yn mawr obeithio cofnodi popeth, gyda'r cymorth Tegan.
En: But Gethin was determined to record everything, with Tegan's help.

Cy: Fe lwyddon nhw i ddal yr arteffactau mewn lluniau, cyn i'r siambr ddechrau dymchwel.
En: They managed to capture the artifacts in photographs before the chamber began to collapse.

Cy: Heb oedi, dyma nhw'n tynnu'n ôl, ddiogel o beryglon pellach.
En: Without hesitation, they retreated, safe from further dangers.

Cy: "Dyma'r storïau gwirioneddol," meddai Tegan.
En: "These are the real stories," said Tegan.

Cy: Roedd gwir ysbrydion hanes yn aros yn yr arteffactau.
En: The true spirits of history lingered in the artifacts.

Cy: Pan roedd yr heulwen yn disgleirio dros y pwll glo, newidiodd y tri.
En: As the sunshine gleamed over the coal pit, the three of them changed.

Cy: Gethin, yn agoriadol ar gyfer cydweithredu.
En: Gethin, open to collaboration.

Cy: Rhian, yn gweld effaith hanes ar ein hunain.
En: Rhian, seeing the impact of history on ourselves.

Cy: A Tegan, a ddarganfu bod stori'n fwy na sŵn, yn wirionedd i gyflwyno.
En: And Tegan, discovering that a story is more than noise, it is a truth to present.

Cy: Roeddent, trwy'r ymdrech drawiadol a'r pystogau cyffrous, wedi darganfod rhywbeth arbennig iawn.
En: Through their impressive effort and thrilling efforts, they had discovered something very special.

Cy: Roedd y gyfrinach dan y ddaear wedi dod i'r golau.
En: The underground secret had come to light.
