[X] Withdraw and destabilize the Reef fully. Conduct a slow withdrawal under the firing lines of the Titans before having the White Scars destabilize the Reef not that they have an idea of how it works. Let the Mitu perish within the warp. Valuable experience has been gained and staying further is tempting fate. *Gain a 10% reduction to warp terrain penalties.*
[X] Push forward and wipe them out. The Reef may not truly be stable, but there is still more to learn. It is a risk, one that makes Oriacarius hesitate. It is a risk that will kill thousands of Astartes now. But is there a chance that it may save more in the future? He does not know the answer. But perhaps another risk must be taken. *Increase experience with warp terrain. Possibility of increasing reduction. Possibility of large losses. Possibility the Reef destabilizes while you are in it. Possibility of facing five Bloodthirsters.*
