With the orders set in place, and the tactical formation having been dealt with, Brother Artenius sheathed his ornate power sword, ensuring that the destructive energies that powered it were quite silent before placing it in the sheath. His bolter was already held at ease by his side, no doubt the xenos would try their hardest to fight the heretics descending on the world, but an ambush was forever a prevalent thought in evne the most zealous of minds. "Remain vigilant brothers, the enemy walks in shadows" He uttered, barely registering the effort it took to speak though his voice carried a stoicism that had endured since the start of the elimination assignment. 

As almost an afterthought he questioned, "I do not suppose anyone here has knowledge about the heretics that assail this blighted world? Their ships seem perhaps, blank, compared to the more common barbarism of the fallen brothers. If I was to hazard a guess, I'd say...Lunar Wolves? Seems too tactical for the bloodthristy ones, and too loud for the backstabbers. Wouldn't question that the latter already has agents on this world, maybe the human population needs a severe looking to..." 

The Librarian was now more or less just trying, perhaps vainly, to make any sort of conversation with his battle brothers as he drew his combat blade to slash his way through a patch of denser foliage. The blade was a full double that which a normal human would consider 'excessive' and it's handle was wrapped with thick alien-hide leathers, the sheer size alone would make many assume it to be more along the lines of a machete than anything else - perfect for the job at hand as it tore through bark and thick branchs as though they were nothing more than wet cardboard. 

With deft motions and haste the Librarian cut, and generally crushed, his way through the flora that blocked the path. Though he pondered just how the Kroot had managed to run off so easily, his thoughts were drawn to the immense chasm that was not a stone's throw from where they now stood. The tracks the Kroot had left, shown them to quite clearly follow into the chasm's murky depths. "It'd seem that those avians finally learnt how to fly...that or there is something greater afoot here..." 

The Librarian paused a moment, then resumed. "However, the Tau leader's stronghold seems to be just on the other side of the chasm... It's either we find a way across, or we go around. The latter takes more time and we may well find foes, but the former is quicker...and far more dangerous... In either case, we shall allow Brother Moros to rejoin us."
