Kurayami Bloodborn
Drunken Savant
Wait, if the corruption comes from the spirits themselves then I just need to find a way to burn the spirits and incinerate anything left over in the crypts and temples(including the structures themselves) using an amount of explosive force simply deemed as, 'overkill' by most sane people. Let's see, a few thermobaric devices per tomb/temple, baradium, detonite charges, C-4, and thermite should solve the problem. And by 'few' I obviously mean 'until not even a grain of sand will fit in the spaces left.' Oh and almost forgot the multiple seismic charges to make sure we can vaporize anything that survived with the above combination. Then I say back up to about a light-minute or so out of the system before the timer runs out. Afterwards we can claim whatever is left of the planet. Sound good? Or does it need more fire? Cuz I can do more fire...
