wh40k.lexicanum.com/wiki/Europae (read directly in a browser on 2026-10-02): 'a Battle Barge in service with the Blood Angels Chapter'; 'During the engagement at Sabien the Europae was under the personal command of Chief Librarian Mephiston' (Deus Sanguinius ch. 1); 'great damage during close range combat with her sister ship, the Bellus, and the Chaos Desolator Battleship Misericorde, the flagship of Warmaster Garand' (ch. 11); her crew kept her intact (epilogue). Lexicanum Arkio and Arkio_Insurrection: Mephiston went 'along with his honour guard, aboard the battle-barge Europae' (ch. 1). NAME-COLLISION CHECK: Lexicanum full-text search for 'Europae' returns only this vessel and pages about the Arkio Insurrection; no index record uses the id or label.
