Logan Grimnar
From Lexicanum
Logan Grimmar has been the Chapter Master of the Space Wolves chapter for over 700 years and is one of the oldest Chapter Master for any Space Marine chapter. Logan like his fellow Space Marines is a fearsome warrior with great martial pride. He has led his Great Company against many enemies of Imperium and has shown a renowned thirst for battle, which some say, even rivals that of their legendary Primarch Leman Russ. He doesn’t tolerate any outside interference when running the Chapter. The Space Wolves have had numerous clashes with the Ecclesiarchy and this has lead to the accusations of heresy and treason.
Logan carries the axe Morkai into battle. The axe is from a Chaos Champion Logan defeated while he was still a Wolf Lord. He had it reforged into the image of Morkai, which is the guardian wolf at the gates of death.
In the First War for Armageddon the Space Hulk, Devourer of Stars, caught Imperial forces by surprise. Even worse the Chaos forces were led by the daemon Primarch, Angron. The forces of Chaos quickly defeated the Imperial forces at Armageddon Prime. Unbeknownst to the forces of Chaos, the Space Wolves were recently assigned to this sector and answered the Imperial forces' cry for help.
By the time the forces of Chaos had come around for a new attack, they found a well organized Imperial force bolstered by Space Wolves. Logan in all his foresight knew that he and the Space Wolves alone would not be able to defeat Angron's force. When the Daemon Primarch led the attack on the Imperial line, Logan played his ace, a full company of Grey Knights. At the great cost of many Grey Knights, they were able to banish Angron back to the Warp. With the defeat of their leader, the forces of Chaos were quickly crushed.
As is standard Inquisition practice for those exposed to Chaos, even for those who have valiantly been involved in fighting against it, the remaining population of Armageddon was rounded up into labour camps and sterilized. While in the labour camps, the original population was left to die while Armageddon was repopulated. Since then, Logan has never forgiven the Administratum for this act.
During Abaddon’s 13th Black Crusade Logan was selected as supreme commander for the defending Imperial forces. Under his command many key victories were won and if it were not for his leadership more of Cadia would be in the hands of Chaos. At the Battle of Kasr Sonnen, Logan and his Great Company and the Chapter Master of the Dark Angels, Azrael, defeated a force many times their size by putting aside their resentment of each other.
