Spear of Telesto

The Spear of Telesto is a relic weapon of the Blood Angels Chapter that was once wielded by the angelic Primarch Sanguinius as his primary weapon alongside the Blade Encarmine during the Great Crusade and Horus Heresy, though it was long believed lost during the latter conflict. Sanguinius was shown using it against the Slaughter-Lord Morroga on the Tapestries of Riga, which hang in the Blood Angels' fortress-monastery on Baal.

Its blade is shaped like an elongated tear with a hollow in the centre to represent the single drop of blood Sanguinius shed when he swore fealty to the Emperor. The shaft is sculpted to show the Primarch as a hooded angel of blood, and beneath that is a Purity Seal with an oath allegedly hand-written by the Emperor Himself. The spear can emit a blast of energy which vaporises anyone who does not possess the blood of Sanguinius coursing through his veins.

The spear was originally thought to have been lost during the Horus Heresy, but the Blood Angels' Battle Barge Bellus was sent to recover it following the discovery of documents relating to its whereabouts on the world of Evangelion, a mission whose outcome had profound consequences for the entire Chapter. The weapon was found among the Ork-held star systems on the borders of the Segmentum Obscurus by a team led by Inquisitor Ramius Stele.
