Wait for our Tech-Priest or Sergeant to deal with the procedures. Head to the chapel to pray. If there is none, order some Guardsmen to find materials and set one up.
"Hoskuldr Hedinson. Confessor of the Ecclesiarchy. Assigned to 666th Vniediken Aerial Infantry Regiment, Platoon III."
Hos walks away after being processed into the Tech-Priest's dataslate. He then proceeds outside while awaiting further instructions. Considering that this world was more lax, he could use his time to strengthen these men's resolve. He gets up on a crate where the men are sitting and gambling. He raises his arms, and yells at the top of his lungs.
"Brave men and women! Are you not better than gamblers, than drunkards? Shape up! You are the Hammer of the Emperor! You are His weapon! A weapon does not gamble! It does not drink! It strikes! It smashes His foes!
If you wish to be absolved, come to me! Listen to what I have to say! Confess! Repent! Through your officers, through the Guard, through the flames of war, through the Emperor himself! You will be reforged in his light! Listen to me, and I will ensure that you are reforged without impurity! Without heresy! You will reflect but a fraction of the Emperor's Light, but you will burn His enemies to the ground!"
Take in any Guardsman for confession or help with his mind after the Chapel is built.
