Briefing

Petra Klarenfield wants an accurate record of what the vault hums and has no patience for a sermon.

Record exactly what the vault hums and return the log without any sermon attached. A Infernal Vault Break can produce a high-risk rare spawn.

Bring me whatever the vault hums, and nothing more; I have no use for a sermon.
Infernal keeps two things carefully: its water and its old debts.
A Infernal Vault Break is connected to this step and can release a high-risk underground rare spawn. I record this step at the Slack-Pool of Infernal.
You've heard it now, and you are still standing, which is worth remembering.
I will write your log faithfully, but I will not write down everything I know.
