Under the sustained and ruthless assault by both bolter and by blade, the avian creatures falter and fail utterly. If they are not sliced into bloody chunks, then they were blown into smithereens by the massed bolter shells which detonated upon their leathery hide, splattering their blood in wide arcs across the forest floor. Truly the Emperor has blessed thy aim and arm, brothers.

Your victory is extremely short-lived, however, as you hear shouting a short distance away in the heavier parts of the forested growth. Out from the plant life, a recognisable squad of five Tau fire warriors backed up by several kroot soldiers, they all tactically skittered about from cover to cover, relying on agility and speed to form overlapping fields of fire and corridors of potential killing zones. The kroot soldiers darted forwards past their deceased allies, caring not for the emotional traumas that would so plague humans in such similar conditions.

“Gue'la!” You hear the, presumably, Sergeant, shouting through his own helmet's sound systems. His voice was wavering, you could almost smell the pervasive odour of fear reeking from him and his men. “Surrender yourselves to the greater good! There needs to be no more fighting!”  He was desperate, far too desperate.

Though they held the line against you, and you will shatter them for this transgression. 
Destroy them.

Brother librarian Artenius spotted these onrushing soldiers, swiftly he shouted in a clear voice. “Brothers! The enemy comes once more!” With this bellowing notification, you hear the Librarian begin to chant loudly, and proudly at the very top of his lungs. His words writhe with raw loathing towards the Xenos, dripping with blackened venomous tones that showed the darkest of loathing towards the blue-skinned aliens.

Raising his force sword, the librarian seemed to emanate a raw psychic power from about his physical form as he placed the full weight of his powers behind the casting. Raising his outstretched hand, the librarian conjured forth four sparking bolts directed purely at the Tau and their kroot allies. All four bolts impacted against the ranks of the Xenos, chaining from each different creature to literally flash cook the creatures. Two of the fire warriors were instantly slain by this barrage, and a further one was wreathed in pain racking lightning. 

“For the Emperor!” The Librarian bellowed with a gleeful tone at the sight of his powers making their full effect. With a zealous speed, he levelled his bolter and fired multiple shots into the mass of aliens, the anointed shells blasting through both armour and flesh like it was nought but paper.

Three kroot and three Tau fire warriors now stand before you.
