France-based costume and prop creator arborealkey will be a featured creator at this year's TennoCon! She'll be crafting the countenance of the final member of The Devil's Triad, Sister Marie Leroux.
Arborealkey specializes in giving life to anything that isn’t supposed to exist in our world, from fantastic swords to awe-inspiring blasters and even event trophies! She surprised everyone with an excellent Valkyr cosplay at Gamescom 2025 and we couldn't wait to collaborate with her on this project.
"I’m pouring everything I’ve learned in the past eleven years into one single project, which is the Wisp Protoframe, Sister Marie Leroux," said arborealkey. "SFX, leather, fabric, wig, electronics, jewelry: she has them all. After over a decade of Warframe cosplay and props, I finally have the experience and resources to do it as I intend!"
If you can't attend this year's TennoCon, you'll be able to enjoy arborealkey's work on the official TennoCon 2026 broadcast on Twitch, YouTube and TikTok.
