Inquistion has voted upon me to hang out with the heretics in order to understand their culture. TELL ME YOUR SECRETS!
*taps Aiolos on the shoulder from behind* You mean to say... you have a button... and when you press it... there's FIRE EVERWHERE?! I. NEED. THAT. BUTTON.
Why? it's just button that unleashes massive amounts of heat and smoke burning everything and every life organsim plus machine on the planet at temperature of 1,000,000 degrees (possibly more) and utterly burns every heretic and xeno on whichever planet the fleet is aimed at.
Now you're practically asking him to contract the Blood Ravens to "acquire" the exterminatus button...
I'm going to assume you're a human that's part of the Inquisition. Here. *Hands A'shen a red button* It also comes with your very own fleet, and regiment of imperial guardsmen. Have fun!
