Pity poor Specialist Bax...
Some facts... My campaign, rather than being agents of the Holy Ordos, the PCs are part of the command squad of a Guard platoon assign to a relief mission on the outskirts of a small hive city (which may or may not be Tranch just prior to the Pale Throng uprising). Specialist Bax is one of the NPCs who rounds out the command squad. He's the vox officer and "company clerk." One of the PCs, Sergeant Mir, is a Nascent Psyker. Specialist Bax was with Mir when she used one of her psychic powers, triggering the psychic phenomena Warp Madness, causing Frenzy and granting corruption to all those nearby... including the unfortunate Bax.
Our session ended with the other PCs recovering the unconcious Mir and Bax, and taking them back to their base camp. Bax was in convulsions and is now drugged into unconciousness himself.
The question, as the title says, is what do to about Bax? Now, Warp Madness only grants 1 Corruption Point, but I tend to take to heart the sidebar Chaos and the Common Citizen, which says that Corruption oints are for PCs and the average mook suffers madness and death. I could just kill him, the grimdark price of a rogue psyker paid by an essentially innocent bystander. I could have him shrug it off and continue with only 1 CP and no lasting ill effects. I could have him survive but be tainted by his brush with the Warp.
I'm curious what others might do with poor Bax...
