For the past one hundred years, Balthazar has always been seen chewing a tentacle in his mouth in the same manner a normal man might chew a cigar.
The tentacle itself is extremely unusual. It is a sickly shade of green, with various brown spots all along it's body. It extends about .3 meters long, and has been known to spontaneously put itself alight. Oddly enough, nothing can put out this flame. No water can douse it, no movement can disrupt it. It has even been known to stay aflame in the void of space. The flame will however, go out just as suddenly as it began, with no explanation. It seems that no matter how long Balthazar has chewed the tentacle, it stays intact.
Some say that it is a trophy of a demon that Balthazar slew, and tried to eat, only to find that it would never come apart, and he has yet to give up eating it. Others claim that it is a relic of the chapter, and that it grants Balthazar superhuman abilities. A few in rival Space Marine chapters, like the Sons of Malice, claim that it is a mutation, and that Balthazar is touched by the dark powers. All that is known, is that, when asked, Balthazar will refuse to answer, preferring the mystery around him.
