Rhwng y sŵn cyson o laisiau yn galw eu nwyddau a'r aroglau melysydd a llysiau ffres yn ysgafnhau'r aer, roedd sgwâr marchnad Caernarfon yn lle bywiog.

Amidst the constant noise of voices calling their wares and the smells of sweets and fresh vegetables lightening the air, the market square of Caernarfon was a lively place.

Tra roedd cleddyfau'n sgleinio a ffabrigau'n chwifio yn yr awel, roedd rhywbeth arall yn denu sylw Eilir wrth iddi gerdded yn brysur.

While swords gleamed and fabrics waved in the breeze, something else caught Eilir's attention as she walked briskly.

Roedd y prynhawn yn synhwyrol ond amhendant.

The afternoon was perceptive but uncertain.

Eilir, apothecari ifanc â breuddwydion o antur, oedd yn ymwybodol o ofid newydd.

Eilir, a young apothecary with dreams of adventure, was aware of a new concern.

Gwyn, masnachwr lleol a chyfaill, wedi cwympo’n wael.

Gwyn, a local trader and friend, had fallen ill.

Roedd ei gwella yn dibynnu ar herb prin a gelwid ef "planhigyn hud" gan hen drigolion y dref.

His recovery depended on a rare herb known as the "magic plant" by the town's old inhabitants.

Ymysg y stondinau, roedd Eilir yn bradychu arwydd o'r planhigyn gwerthfawr.

Among the stalls, Eilir was searching for a sign of the valuable plant.

Ond roedd y marchnad yn gorlawn, ac roedd llwybrau'n gymysg byddin o fedi.

But the market was overcrowded, and pathways were a tangle of reapers.

Roedd hi angen cymorth i fynd y tu allan i furiau'r dref lle rhoddir planhigion fel hyn.

She needed help to venture beyond the town walls, where such plants grew.

Felly, penderfynodd droi at Rhys, ei ffrind plentyndod a dywyswr fedrus.

So, she decided to turn to Rhys, her childhood friend and skilled guide.

"Rhys, mae’n rhaid i ni fynd at y thicket tu allan i’r farchnad," meddai Eilir yn ysytraig.

"Rhys, we must go to the thicket outside the market," said Eilir urgently.

Cytunodd Rhys, gyda'i chalon yn tyner wrth feddwl am yr her sy'n aros amdanynt.

Rhys agreed, his heart softened by the thought of the challenge awaiting them.

Ar ôl taith drwy'r sgwâr heintiedig a cherdded tuag at y thicket, cwelodd Eilir y planhigyn tra'n disgleirio dan y golau haul.

After a journey through the crowded square and walking towards the thicket, Eilir spotted the plant shimmering under the sunlight.

Ond fe ddarganfu wrth ddod yn nesaf bod manw oedd yn gwarchod y ddaear gerllaw.

But as she came closer, she discovered a magpie guarding the ground nearby.

Gan wybod bod rhaid gweithredu'n ofalus, gwnaeth Eilir gynllwyn a chyflwyno rhosyn chwerthinllyd fel tyniant i'r aderyn chwilfrydig.

Knowing they had to act carefully, Eilir devised a plan and presented a comical rose as a distraction to the curious bird.

Gyda phob symudiad yn ofalus, llwyddo i sicrhau'r dail angenrheidiol.

With every movement being cautious, she managed to secure the necessary leaves.

Daeth Rhys ac Eilir nôl i'r farchnad, lle paratôdd Eilir'r cymysgedd gyda hiwmor enbyd.

Rhys and Eilir returned to the market, where Eilir prepared the mixture with anxious humor.

Roedd y cymysgedd wedi'i fwyttydd a Gwyn adfer yn gyflym, gan ddwyn diolchodd y dorf gwefreiddiol iddi.

The mixture was consumed, and Gwyn recovered quickly, earning Eilir immense gratitude from the thrilled crowd.

Wrth wylio pobl y dref yn ddiolchgar, sylweddolodd Eilir fod ei dewrder newydd wedi agor heriau newydd tu hwnt i'r oll shee.

As she watched the town's people express their thanks, Eilir realized her newfound courage had opened up new challenges beyond everything she thought she knew.

Meddyliodd am y byd y tu hwnt ac addawodd chwilio am ei antur nesaf.

She pondered about the world beyond and vowed to seek out her next adventure.

Efallai dim ond apothecari ydy hi, ond erbyn hyn hefyd, roedd hi'n anturiaethwr wrth galon.

Perhaps she was just an apothecary, but now, she was also an adventurer at heart.
