Warhammer 40,000

The Kill-team is busy tracking a signal coming from what appears to be a saviour beacon on a desolate planet or moon. As they close in on the signal, they can see that the source belongs to a crashed shuttle or other conveyor, and that it has been there for quite some time. The smell of carrion fills the air, and scattered bones and carcasses litter the area outside a great rent in the side of the craft. Due to a cracked plasma drive, auspex scans are unable to penetrate into the craft. It’s dark inside the rusting hulk, but signs definitely point to a Diablodon within. As the Battle-Brothers make their way through the craft in their search for possible survivors, they discover a broken cage within the cargo hold. It appears that the creature escaped and attacked the crew before they could reach their destination. Do the valiant members of the Deathwatch choose to avenge the dead shuttle crew, or do they allow a potentially hostile xeno-beast to roam unchecked?
