Glenroy's Akaviri Katana is a unique weapon wielded by Glenroy, a member of the Blades present during the tutorial of The Elder Scrolls IV: Oblivion. It is the second unique weapon obtainable by the Hero without the use of console commands.
During the Final encounter against Mythic Dawn Agents in the Imperial Prison Sewer, as the Hero is alone with the Emperor, Glenroy is slain. He drops his Akaviri Katana, which the hero can pick up and wield. Baurus removes the katana from the inventory immediately after class creation.
When the Hero arrives at Cloud Ruler Temple with Martin, he rewards them with +1 to Blade, Block, and Heavy Armor for recovering the blade. After, the katana is given a place of honor in the Temple. It can be found on a display as a mantlepiece.
