The void is a cruel mistress, in my time with the Explorator fleet of Archmagos Paracelsus Thule, I have born witness to horrors the likes of which you had best pray never violate imperial space. I spent my early life among my brethren serving the Omnissiah deep in the arc ships depths in the research labs. We must always be seeking to recover the wonders of achievements lost into the chaos of history, I focused my will entirely on deriving benefit from the archeotech remnants we recovered and coaxing the ancient machine spirits back into action. As I progressed in my training and my talents became more apparent I began serving aboard expeditionary survey and retrieval missions into the depths of void hulks and dead worlds. I have learned to trust my own judgment and unless you can make a solid case supporting your position you had best not besmirch my decisions or speak ill of my actions.
All lives have value, that value can be equitably calculated if enough information is known about the individual, the utility of this valuation is objectively apparent. In expeditionary endeavors it is often found that the optimal outcome of hazardous situations requires those whose lives have less value to sacrifice themselves to preserve those whose lives have greater value. It is a rare occurrence that a retrieval expedition does not make its return only by the grace of the Omnissiah and the sacrifice of those who, their flesh laying tattered and torn wearing shirts soaked red with blood, shall remain consigned to the void.
