Warhammer+ unveils Adepta Sororitas: Penitence teaser alongside marble-paint tutorial

Warhammer Community promoted an "exclusive teaser of the new Warhammer+ animation Adepta Sororitas: Penitence coming soon" on 18 February 2026, offering the first official extract of a Sisters of Battle story and bundling that extract with hobby content. The Community post explicitly tied the animation tease to a marble-paint effects tutorial, writing "Paint marble effects from this week’s Armies of Renown, and get an exclusive look at new animation Adepta Sororitas: Penitence."

Warhammer TV mirrored the Community promotion by uploading an intro sequence to its YouTube channel with the caption "Check out the intro sequence of the thrilling Warhammer 40000 animation, Adepta Sororitas: Penitence, coming to Warhammer TV soon!" The video and the Community page both use the phrase "coming soon" and do not list a concrete release date or episode schedule.

Secondary outlets filled gaps with additional claims. Bubbleblabber reported that Penitence is a new three-part series produced by "the same creative teams responsible for the visually stunning Pariah Nexus," and summarized the plot: "Penitence is an Adepta Sororitas story, following a squad of Battle Sisters as they deliver a sacred relic to a would-be site of pilgrimage. Of course, things don’t quite go to plan." Bubbleblabber ran the interpretive headline "Warhammer+ Teases Adepta Sororitas: Penitence Original Series But Seemingly Pushes It Back A Tad," implying a scheduling wobble though it did not provide a new date.

Fan chatter added more uncertainty. A Reddit post claimed the teaser was "set to release next week," but the snippet lacks a timestamp and is not corroborated by Warhammer Community or Warhammer TV. The only verifiable timing detail in official channels remains the 18 February 2026 Community promotion and the Warhammer TV upload labeled "coming to Warhammer TV soon."

Warhammer Community's post also included practical viewing notes and marketing details: the teaser is hosted on a third-party video player that requires cookie consent, "This video is hosted on a third party website, which may be using cookies", and the page reminded readers that "Warhammer+ subscribers also receive other benefits, including discounts and offers from Warhammer Licensed partners." The teaser was presented alongside other Warhammer TV roster items such as a Tyranids vs Death Guard biological battle report and features on Black Library authors.

At present the confirmed facts are narrow: Warhammer+ and Warhammer TV have released an official teaser/intro extract and Warhammer Community paired it with a marble-painting tutorial on 18 February 2026. Claims of a three-part format, a Pariah Nexus creative-team connection, and any specific release date come from Bubbleblabber or unverified Reddit posts and remain unconfirmed by Warhammer+. Until Warhammer+ publishes a full press release or credits, the teaser stands as an exclusive first look and the marble tutorial as the immediate hobby tie-in for Sisters of Battle fans.
