Riot Games has strengthened its partnership with Fortiche Production by making a new equity investment in the animation studio behind Arcane.

The League of Legends creator announced the deal, which closed earlier this year, in a blog post on March 14.

The terms of the investment remain undisclosed, with Riot saying that it now holds a significant but non-controlling stake in Fortiche. Brian Wright and Brendan Mulligan, who serve as the company’s chief content officer and director of corporate development respectively, also joined the animation studio’s board of directors.

“In working with Fortiche, we collaborate to push the boundaries of what’s possible and raise expectations for how games can be represented in media,” Riot Games CEO said in a statement. “As proud as we are of Arcane, we know the best is yet to come.”

Fortiche Production, founded in 2009, employs 350 people across its offices in France and Spain. The studio has been collaborating with Riot for almost a decade, working on different trailers, videos, and cinematics. It is best known for award-winning animated series Arcane, which was developed and produced along with the League of Legends makers.
