The escape from the weird xenos labratory brought Fayak and her entourage into a tunnel right above. Unfortunately the vile genestealers were already in ambush and quickly overwhelmed Bethor. The rest of the group kept the creatures at bay while Azrael opened up a metal grating in the side of the tunnel and Ambrosius covered the escape of everyone. Using a smoke greande and his psy power to shroud the groups escape path the primitive claw beasts are stumped on how the prey could have disappeared so suddenly.
