Cassian Vaughn

"You come seeking our father, but he is not here. I searched for him on the field of battle until they struck me down with a sword of flame that scorched the very heavens, and yet I did not die. I searched for him in the endless vaults of the dead where the crushing blackness tore at my very soul, and yet I endured. I was tested once again through the crucible, and I tell you this -- Vulkan does not walk among the dead!"

– Cassian Vaughn, first Lord Commander of the Salamanders.

The Iron Dragon, and the Eternal Flame. (This actually depicts the current interred marine in the Dracos Revenant, Bray'arth Ashmantle.)

Cassian Vaughn, later christened and reborn as Cassian Dracos, was the legion master and lord commander of the Salamanders during the Great Crusade and later the Horus Heresy.
