in regards to the perpetual ability needing psychic power to use, that simply doesn't hold any water: vulkan was beheaded and killed. there was zero psychic output from vulkan, on any level, with him being dead and all, so if the perpetual ability needed psychic power to be used properly then vulkan would have stayed dead.

if emps is the source of vulkan's ability then it stands to reason that emps' ability would be far greater - if it took vulkan within 24 hours to grow a new head then we could surmise that emps would regrow a head in less than 6 hours, and the injuries sustained by emps from horus would have started to heal almost instantly.

i agree though that emps would never ally with chaos under any circumstances, which would be unfortunate since they would be the only way to utterly anihilate the tyranids - a war of attrition loses it's attraction to tyranids when there's no bio-mass to replenish their losses. but i have to disagree that emps could outsmart tzeentch: tzeentch has spent millions of years, maybe billions, outsmarting everything and everyone in every way concievable. it's his entire existence to outsmart. saying emps could outsmart tzeentch is like saying he could out-kill-maim-burn khorne, or out-deprave slaanesh :P
