[40k/HP] I am an Inquisitor of the Ordo Malleus. I have found myself on a primitive planet, whereupon I discovered a secret society of rogue psykers. How much of a threat are they to the Imperium of Mankind?

Their sorcery appears astonishingly weak compared to the psykery I am used to, especially my own gamma-level psychic abilities, however they have somehow managed to keep hidden from the entire non-psyker population of this planet for centuries at least.

Does the planet need to be purged? If so, what would be the best method to eliminate this psyker presence? Could an exterminatus be required?

The Creed says to distrust the Psyker, not to kill it on sight. Were we to kill the Psyker you wouldn't be alive now, would you?

The question is if they will follow the Imperial Creed and accept their place in the Emperor's great plan.
