Rinwen - The Holy & Illuminated Mysteries of Britain

You know that the world needs wisdom-keepers of the sacred and ancient ways.

Rinwen is for all in search of ancestral belonging, cultural grounding, and a more intimate relationship to land, soul & cosmos through the sacred traditions of Britain.

  • Wake up knowing the ancient myths of Wales, England, Cornwall & Brittany, and take them to your children, your friends & your community.
  • Live by the animist philosophies and embody the traditions born from these lands and known by the ancestors of these isles.
  • Speak and sing in the ancient languages, listen to and learn folk songs of old and new.
  • Follow your own threads & weave what you discover into your personal, creative, and spiritual practices.
  • Learn from people who walk the land, speak the ancient languages and are devoted to the old wisdom traditions through authentic, trustworthy teachings, research and embodied spiritual practices.
  • Know that you are one thread in a web of relations that are blooming into a new tapestry of belonging, honour of the planet and our ancestors.

For all on the land, in the diaspora, or strongly called to take on this work.

STEP INTO RINWEN

Perhaps you've looked around, gained guidance from far-off traditions, and know there's more to uncover within the roots beneath your feet, or through your lineage.

In Rinwen, you will move from passively consuming content about the wisdom traditions of Britain to embodiment, remembering & practice.

What is Rinwen?

Rinwen is a centre for learning, storytelling, mythic embodiment, ritual, creative practice and ecology, focused on the sacred traditions of Britain, looking specifically to Wales, England, Cornwall, & our Brythonic family across the ocean in Brittany.

Here, you will build a sacred record of lore, wisdom & embodied practice to weave into your personal work or take into your community, as a torch-bearer of these ancient roots; of land, soul, and myth.

Inside Rinwen there is a pathway of live lessons for guidance while you follow your own threads, alongside a living library of resources, and lessons from guest teachers, artists and wisdom keepers devoted to exploring the animistic wisdom traditions of Britain through authentic teachings, deep research, and devoted living practice. You will build a practice and body of knowledge that you can take into the world.

JOIN RINWEN

You know that your role is to become a devoted carrier of the ancestral traditions of Britain; Wales, Cornwall, England and Brittany. You wish to become a keeper of myth, lore, legend, belief, ritual and practice.

  • You want a space with information and sources that you can fully trust, learning from people living the traditions of the land.
  • You’re eclectic and expansive, a lover of study, the arts, and creative practice, with an embodied relationship to the land wherever you are.
  • You learn through creative practice and embodiment; drawing, song, story, timelines you can see and feel.
  • You're a practicing artist, musician, facilitator or practitioner who wants to root into these traditions into your practice.
  • You're willing to discover and research yourself, guided to the original sources.
  • You want no BS, no historical or mythic misinformation, romanticisation or dogma. Only reliable sources, and a space to explore.

From uprooted confusion to deep grounding and belonging. From seeker to keeper.

Do you host in-person events?

Caer Sidi isn't all online.



The most important thing we can do alongside reclamation of knowledge, is gather in person. Inside of Caer Siddi, members can share and promote in-person events, where a list of gatherings, ceremonies, and circles around the sacred pathways of Britain are promoted, both inside of Caer Siddi and in Stella's monthly newsletter, that will soon turn into a webpage.

Rather than moving from one to the next, each strand is woven throughout your journey in Rinwen, allowing your understanding to deepen through the changing seasons, the land, your embodied practices and what you discover. The strands are distinct, yet deeply interwoven. As we explore the sacred pathways of Britain, they naturally overlap, informing and enriching one another.

III

The Mythic Self

Clarity

The Principles of Rinwen

There is no dogmatic path to follow here. You follow your own threads, guided by original sources, research pathways and guest teachers.


 

This Is

A centre for study and embodied practice, rooted in Ecological, Ancestral, & Mythic belonging, for the modern world. Knowledge found through original historical sources, creative interpretation, lived experience, and your own personal callings. Learn from teachers who walk the land and are devoted to these living cultures without misrepresentation.

This work is not only about reconciling with the past but about changing how we think and behave today. Decolonial work is another thread woven through everything in Rinwen, dismantling and acknowledging colonial ways of thinking and behaving within ourselves and our communities, knowing that colonialism is not history, it is still here. In Rinwen, we aim to dismantle individualistic and materialistic ways of seeing each other, community and the Earth, returning to a baseline of openness. We have an upcoming workshop on Decomposing Whiteness with Kimber Simpkins.

This Is Not

A claim to fully know the beliefs of the past, or an ancient tradition to be initiated into. Rinwen does not offer a prescribed spiritual path, you are guided to find your own callings. We aim to avoid romanticisation, appropriation or misinformation, and to build new stories, songs and practices where old ones aren't found. Rinwen is open to all.

 What People Say 


 

"So wonderful to celebrate this time - a real celebration over multiple days, more than a five-minute fancy, deep ceremony, deep reverence in community, people you're seeing every day, honouring and celebrating."

- Alys, Mystic Cave, Samhain 2025

"I stumbled upon you at a time when I have been getting a powerful urge to connect with my British roots. I spent many years looking into different paths, but always as an observer. Always felt something was incomplete."

- Violetmoon751, YouTube

"Tonight's call was deeply moving and enlivening in ways still integrating but clearly impactful."

Abigail, Taliesin's Awakening

"I am absolutely enraptured and this feels like home. Thank you so much for bringing this course to us!"

— Mystic Cave member, Samhain 2024

"Coming home to our ancestral lands can indeed simultaneously happen inside of us and wherever we are situated on Mother Earth."

— Mystic Cave member, Beltane 2025

"I joined to connect with my ancestral heritage, so much seems lost and hidden. I wanted to know who I was and to deepen into this through knowledge and embodiment." 

- Helen, Awen Awakens, Feb 2026

I’ve spent the summer traveling the land, telling tales of my ancestors and the Earth, sharing the mysteries of Awen and the Cauldron of Inspiration, rooting people into the landscape through sensory journeys and poetic quests inspired by the ancient Bards, but most importantly, people have been wonder-struck by the wisdom that lives within the roots they walk, and the waves that crash upon their shores.

Rinwen was born, after hosting many seasonal offerings that left people wanting a deeper, longer, and more intimate community.

In 2018 I was preaching 'mother earth connection' while my practices were disconnected from my own ancestry, land and culture. Today, I'm a facilitator, speaker, storyteller and podcast host, sharing the ancestral wisdom traditions of Britain through study and embodiment.

I currently live in the Welsh as an artist, storyteller, and facilitator. As a child, my family owned a vegan health-food shop, and in my late teens I ran a wholesale crystal business, cleansing with foreign herbs, inspired by spiritual traditions not of my lineage. Then I found a book on Celtic art in my university library, and everything changed.

This endeavour into my own heritage began when I tapped into my grief and longing for the rich, mythic culture buried within the depths of my ancestors' suppressed historical past. My mam and dad both passed away before I was 25 due to suffering with mental health, now, bringing deep belonging and awe to people is my north star and greatest mission, and I have found this through Earth-based, ancestral spirituality.

I am currently I'm pursuing a Master's Degree in Illustration and Animation, deep-mapping my local river, the River Taff, through animistic visual storytelling, researching similar traditions throughout time. This is building the foundation for Rinwen.
