Under Her Black Flag
An illustrated interactive map trail and story experience through York



Overview
in 2024 our studio was awarded the Creative Catalyst research and development grant to bring to life Under Her Black Flag (UHBF) from story concept to mobile app prototype. An original story by Lást.
UHBF is a story based trail based in the historic city of York, taking people on a journey to uncover hidden city stories, and discover lesser known histories. With challenges at various locations across the trail, the balance in this ambitious project at every junction was creating something that felt authentic and old, whilst innovatively housed on app. How could we make people feel like they were reading a story book whilst walking through the city? This meant functions that ran smoothly, but graphics that were weathered, imperfect and gritty, just like the experiences pirate main character.

The studio was at the helm of this monumental project, directing and managing the wider team whilst producing the story, graphics and visual identity. Following extensive concept refinement, Angel (of Lást) wrote the character driven story narrative, and produced detailed development scripts for the development team, alongside the composer and voice actors. The trail sees our main character, escpae rogue Bonny, on her journey out of the city.
Lást painstakingly hand drew a wide suite of over 60 illustrations to accompany the story that unfolds across the city in our signature heritage ink style, perfect for a story set in 1700. Engraving style line work built this world out, with strong cross line textures and a story-book quality to them.


The illustrated map for the trail was drafted traditionally, before being rendered for digital use. Game developers took the analogue creation and brought it to life in the prototype with functions like GPS tracking and structured game play. The wanted poster features the main character in the trail, escaped rogue Bonny, which was a crucial part of the prototypes prologue.
The unique point to explore in the R&D project was how to design a map that can go beyond simple navigation, but house the entire story and experience. Having drafted the map in house, the development team at BetaJester rendered it into Unity, developing the map as the beating heart of the app. With the ability to track the user around the city, users could follow the trail, or go off track to uncover bonus stories through out York.
We explored how to bring more than the history of the city to users, developing the outlines for challenges and riddles that must be completed at each location on the trail, successfully creating a game play structure that can be built out in the second phase of development.


We brought our original story to life with hand drawn illustrations. The prototype is a tribute to a period in time, full of traditional craft and mystery. The aim was to research the limits of illustration, and how we might make the experience feel more interactive without the resources to explore immersive technology. To overcome this, we opted to produce two and three stage illustrations in. a slowed animation style sequence.
This project was the most ambitious the studio has ever embarked on, pushing our story telling expertise to new heights, and our illustration skills to their limits. User testing on the app prototype was insightful, and has formed part of our detailed strategy to take the prototype to the next level in wider testing, and eventually to bring it to market.
The trail prototype celebrated the use of traditional crafts accessed through mobile. For the first time in our design careers, it highlighted the opportunity that immersive technology could bring to our practice. Budget and time didn't allow exploration of these exciting technologies, and how they might be used, pushing Lást to explore them to understand their place in the future of interactive story telling.
