Following the death of Sanguinius at the Battle of Terra, it was handed down to the Blood Angels' first post-Second Founding Chapter Master, Belarius, who received it from the hands of the Primarch himself. The blade's powers are said to only be available to those who possess the genetic inheritance of Sanguinius.
Alongside the Spear of Telesto, Sanguinius wielded the Blade Encarmine as his primary weapon throughout his life, and used the blade in combats with the Bloodthirster Ka'Bandha, the Keeper of Secrets Kyriss and the daemon of Chaos Undivided Madail.
At some time in the 41st Millennium, the relic was lost to the Ork Warlord Garshul the Destroyer during a battle with a Blood Angels force under the command of Captain Leonatos. Leonatos was exiled from the Chapter by Commander Dante himself until he recovered the lost relic blade.
In his quest to recover the Blade Encarmine, Leonatos and his group of fellow exiles tracked down the Ork Warlord's fleet, only to discover the Warlord himself had become a host for a daemon of Tzeentch. Following the daemon's Traitor Marine allies into the Eye of Terror, Leonatos once again searched for the sword across a Daemon World. He eventually recovered the blade, but at the cost of his own soul. The sword was returned to Baal by the two remaining Blood Angels exiles, who refused to rejoin their brothers. Instead, they themselves undertook a quest to rescue their commander from servitude to Tzeentch.
