Thalia: Beyond the Helvault was a four-card Secret Lair drop dedicated entirely to Thalia, Guardian of Thraben, chronicling pivotal moments from her story on Innistrad. Each card featured different foil alternate artwork by Magali Villeneuve or Johannes Voss, depicting events including the destruction of the Helvault, Thalia's confrontation with the council, her alliance with the Geist of Saint Traft, and her battle against Brisela. The drop stood out as a character-focused release that turned a single legendary figure's story into a cohesive four-card art collection.
