Just noticed this:

Commander Bio: Born in one of the [b]Fenrisian hive-spires[/b], he was recruited into a local gang when he was just 4, running messages for them. He grew up into a ruthless juve, but was quickly recruited into the local guard, as he had always had a thing about REALLY BIG GUNS.[/quote]

Fenris doesn't have any hive-spires. That planet is purposefully kept in the medieval age by the Wolves to breed tougher warriors. Perhaps you mean a hive spire on a planet that is a Space Wolves Protectorate?
