Even for a Space Marine, Darnath Lysander has led a long and bloody career. As sergeant, he was credited with the successful defence of Colonial Bridge and hailed as the vanquisher of the heretics of Iduno. As Captain of the 2nd Company he led the storming of the Eldar cruiser Blood of Khaine and rescued the Haddrake Tor Planetstrike from disaster. For two centuries afterwards, Lysander led the Imperial Fists' 1st Company with distinction, earning the highest praises his Chapter could bestow. After having once being thought to be lost in the Warp, then having returned and fought his way back from an Iron Warriors stronghold, he was restored as the 1st Company's Captain and a glorious hero. He's got a massive hammer and a massive shield - if you haven't guessed what Captain Lysander is for by now, then we'd be very surprised. As the Captain of the 1st Company, Lysander is an incredibly powerful character, and extremely resilient to boot - back him up with a unit of Assault Terminators and watch the carnage begin. Once Lysander's in combat, he won't be satisfied until the enemy are dead at his feet.
