Working as a blacksmith's apprentice, Declan Finney's master was secretly a member of the Brimstone Society. One day, Declan witnessed several demons attacking his master. All that was left of his master was a smoldering brimstone. After the demons had left, Declan threw the brimstone into the fire, with which he forged the Twin Blades.
He used the blades for himself, during his time in the Brimstone Society. Fighting alongside agents called Spectre and Ghost, he called himself agent Wraith.
Retiring in Ireland, he met a young BloodRayne who was searching for her biological father to kill him. She had killed a troublesome wolf on Declan's land. He took her in and told her about his own vampire troubles and his time with the Brimstone Society. A demon showed up on Declan's door. Despite working together with the Twin Blades, the demon still managed to kill Declan. After killing the demon herself, BloodRayne kept the Twin Blades.
