Organise a sustainability team building

The sustainability team building that makes people want to act

Tackling corporate social responsibility through lectures or guilt-driven messaging rarely motivates a team. To genuinely involve your people, you have to reach them emotionally. L’Héritage des Gardiens is an immersive team building activity built around awareness-raising and responsible development. Drawing on our shared attachment to the landscapes of our memories, this game turns your CSR strategy into a powerful driver of team cohesion.

Why choose this game for your CSR event?

Whether you’re rolling out your sustainability strategy (CSRD targets), adding energy to an annual offsite or hosting an awareness day, this format delivers a memorable collective experience.

Emotion as an answer to solastalgia

The game speaks to a major social concern: the desire to preserve and pass on the environment that shaped our lives. Against a feeling of environmental powerlessness, the adventure restores meaning and the will to act.

Real action for the planet

Split into teams around themed boards (biodiversity, water, renewable energy), participants get to grips with the values of sustainability hands-on.

A collaborative quest

To buildteam spirit and strengthen cohesion, employees step into a heroic-fantasy world: the Guardians of the Landscapes are bowing out and searching for their successors through the Quest for the Keys of Sharing.

What our clients say

Jowana MANSUELA, Head of Communications, Générations Mouvement

Wonderfully smooth support in organising our 2026 offsite. Huge thanks to the whole Arcane team for the quality of the facilitation and their infectious energy!

We called on Arcane for our annual offsite on the theme of living and working well together. We wanted a playful session to bring our team together and shift some habits within our management team. Many thanks to Arcane for recommending this activity — everyone loved it!

2024 was a chance for us to review our employees' working conditions, and the semi-customisable format won us over! It was hilarious to see one of our directors turned into a suitor for Bowser. The session really broke down professional barriers and brought everyone closer!

Great fun, people connected, and the difficulty level suited everyone.
