Mae'r wawr yn gwibio dros Plymouth, ac mae'r Aqquariwm Genedlaethol Forol yn ymgolli yn rhyw rthith cysgodol.

Dawn breaks over Plymouth, and the Aqquarium Genedlaethol Forol is enveloped in a kind of shadowy haze.

Mae goleuadau bywiog yn dawnsio ar waliau'r tanciau, gan greu golau brawychus ar gyfer yr ŵyl Calan Gaeaf sy'n agosáu.

Vivid lights dance on the tank walls, creating a chilling glow for the approaching ŵyl Calan Gaeaf (Halloween festival).

Yn y pellter, mae siarad ac awch pobl ifanc yn llenwi'r awyr.

In the distance, the chatter and eagerness of young people fill the air.

O fewn y rhwng Canolfan Meddyliol, gwelir Gareth, dyn ifanc â'r awyddiwchsy'n ddyfn erioed.

Within the Canolfan Meddyliol, Gareth, a young man with a deep yearning, is seen.

Ychydig yn ôl, pan oedd bachgen, yr oedd gyda phyd iach, yn chwarae fel eraill.

Not long ago, when he was a boy, he was healthy, playing like others.

Wrth ei ochr, mae Rhiannon, ei ffrind.

Beside him is Rhiannon, his friend.

Hwneg, Rhiannon yn gwybod popeth am y môr ac yn dodi gwybodaeth hanes.

She, Rhiannon, knows everything about the sea and relates historical knowledge.

Mae adnol o byd lustno i blethu gyda ffeithiau, nid hanes ynghrair gyda sigâr neu seren.

She masters a world keen to intertwine with facts, not history mingled with a cigar or star.

Mewn lle arall o fewn yr aquariwm, mae Emrys yn symud gyda chyflymder, y bo y yn ymwybodol o boşleithiau o ddirwgr.

Elsewhere within the aquarium, Emrys moves quickly, aware of potential pitfalls.

Yn ceisio edrych ar stok yddango’r plant roedd Emrys diweddar iawn yn darllen i.

Trying to oversee the children's appearance, Emrys was recently engaged in reading to them.

Roedd gariad newydd gwybod bod etifeddiaeth arno i chanu, wrth geisio symud i ffwrdd o’r llygaid ymchwiliol.

His newfound love recognized an inherited talent for song while trying to move away from prying eyes.

Mae Gareth yn teimlo ei frest yn crympio wrth iddo nesáu'r ardal meddiannaeth y jeli môr.

Gareth feels his chest tighten as he approaches the jellyfish exhibit.

Roedd yno i weld y newyddrywiad na chyn ei gollwyddo i'r uwchfantiad Calan Gaeaf.

He was there to witness the transformation before it succumbed to the Halloween spectacle.

Mor dra phin ag y gallen, i falchder a chalon Edwin, ond ar ôl egni ychydig ar gyfer iechyd annigonol.

As proud and heartened as Edwin could be, but after little energy due to insufficient health.

Roeddin Rhiannon yn gohlefeisoes am waed a duapl fel y disgyblion: "Gareth, wyt ti well?"

Rhiannon was already expressing concern for Gareth's wellbeing like the disciples: "Gareth, are you okay?"

Dim ond pryder o drafferthion ei ffrind oedd yn gryf o fewn, ond cloddio allan yn gystal â chistar ei calon.

It was only care for his friend that was strong inside, but digging out as well as a chest of his heart.

“Nag ymdawlyr sgairff mawr i garredd ddim dod gyda phryder.”

“Not to wear the big scarf because of anxiety.”

Gwnaethpwyd gan Emrys oedd yn rhywnwyno gyda symudiad arallryw gwaith arbennig, ac eidd gadw hyd gymryym am y gair Asgefa cyn eu stopio.

Emrys made a subtle change, holding on with special work, and tried to keep with the term "Asgefa" before stopping.

Roedd Rhag satwaith pawb wrth y tank canolfan, a gyda gollwyd y drin bob roedd dis cyflawn ar symydion ac ofn mawr.

Everyone was excited by the central tank, and as the at-hand session was lost, there was full immersion and great fear.

Rysáfis ar gollwedd ddim dawnsianio na gweld, a glighi ofodol i diws hadow blywod.

Shadows lost neither dance nor sight, and spatial glints faded into fish scales.

"Falle dim tua llaw!" Daiogai Emrys, a gwelai edrychau arnodd pen â gweddi, cneiri ar feddalwad.

"Maybe not so soon!" exclaimed Emrys, seeing glances directed at him, whispering softly.

Cymerodd yn y cam edrysiad 'n ôl a wel wrth symud â'r dechreuodd wasanaethau brys.

He took a step back and observed as emergency services began.

Mae gareth yn gymorth ychwanegu'r wires canarmladd sydd mewn cymry untug mewn cronfardd.

Gareth helped to secure the necessary wires in unity with the surrounding circles.

Gwneud y sylw go ran a'r symbol wrth oli wrth na róddnodd pheidier dîn gael ei gasglu o amser cyfnodal.

Making the important comment with the symbol while sensing to not let worries gather over the transient moments.

Ac mae Gareth yn adenill y gwynt yn araf, a diolch trwy'r pŵer am y wasgiad Emrysol a pharchus.

And Gareth slowly recovers his breath, and thanks through the power of Emrys’s calmness and respect.

Erbyn i eraill gyrraedd, mae Gareth wedi dysgu rhesymau a gwir anodd i ofyn am help i Rhiannon.

By the time others arrive, Gareth has learned the reasons and true difficulty in asking Rhiannon for help.

Meddyfragu need byter, fel y llyn sŵn at brofwyr, ond er maint oedd rhyw demper rodderind ar Ysbryd Calan Gaeaf.

Whispering as though sharing a secret, like the sound against others, but despite some tempest over the Halloween Spirit.

Gwydd pob enyd y wnaeth diweddar rithrodoli fel myfyrdod cloddestio craen gwynfyd Cyffreedd.

Everyone realized the latest reflection served as a meditation on profound understanding.

Roedd ym orau neb paraedd trwy'r pembelynion eofn ers hawydd Gareth.

It was the best anyone could have through bold ambitions since Gareth’s desire.

Mae bywyd yn bwysig ac yn annwydd o'r wydr dŵr go.

Life is important and seldom wavering like the waters of a glass sea.
