In 1978, Shallcrass joined an
Alexandrian Wiccan coven, being initiated a High Priest the following year. During the course of that year, he had been writing seasonal festival rites for the coven. These were heavily influenced by his studies in Druidry. By the time the festival cycle was complete, the coven's celebrations had become so Druidic in flavour that the members agreed to stop calling themselves a coven and become instead a Grove; the Grove of the Badger. This is now seen as the Mother Grove of the British Druid Order (BDO). Over the years that followed, the material written for the Grove of the Badger was revised and added to. At the end of the 1980s it began to be published and bring the BDO to wider attention. He married Eleanor Kilpatrick, an Occupational Therapist with the NHS, in 1985. In the early 1990s, Kilpatrick and Shallcrass met and began a continuing friendship with Philip and Stephanie Carr-Gomm, chiefs of the
Order of Bards, Ovates and Druids. Philip Shallcrass began to lecture on Druidry at a series of conferences on New Religious Movements. In 1992, he became editor of ''The Druids' Voice: the Magazine of Contemporary Druidry''. In 1993, at the invitation of
Tim Sebastion, founder of the
Secular Order of Druids, Shallcrass composed a ritual to be performed at a multi-faith conference Tim had organised among the old stone circles of Avebury in Wiltshire. This resulted in the formation of the Gorsedd of Bards of Caer Abiri, which grew over the next few years to become what Ronald Hutton described as the "central event" of the New Druidry, initiating many people into the Bardic grade. A detailed account of the first event was published in The Gorsedd of Bards of Caer Abiri Newsletter No. 1, where Shallcrass took the role of Chief Druid (equivalent to Master of Ceremonies) with the assistance of
Philip Carr Gomm of the Order of Bards Ovates and Druids. Another detailed account of the Gorsedd was later provided in the Pagan Federation's journal Pagan Dawn. In 1994, following what he described as a powerful vision in a sweat lodge, Shallcrass adopted the Druid name, Greywolf. In 1995, he began to work regularly with Emma Restall Orr, who became joint chief of the BDO. Together, they lectured, hosted workshops and rituals, wrote new material for the Order, and appeared on TV and Radio in the UK and elsewhere. The "shamanic" form of Druidry pioneered by Shallcrass with the British Druid Order resulted in bringing the shamanic vision of the World Drum Project to ceremonies at Dragon Hill, below the Uffington White Horse hill figure in Oxfordshire, and at
Avebury in Wiltshire. Shallcrass has created a series of distance learning courses on Druidry for the British Druid Order covering all three grades of Bard, Ovate and Druid as a series of monthly booklets. The course comes with recommendations from prominent figures including Professor Ronald Hutton and Robin Williamson. The
closing ceremony of the
2012 Paralympics included text from a 1997 Gorsedd ritual written by Philip Shallcrass and
Emma Restall Orr. Shallcrass has been active in areas of ancient technology such as roundhouse building at the Wildways retreat centre in Shropshire. ==Books==
