More about this voice

What makes it cold

Part	Setting	What you hear
Depth	Pitch -5, Tone -3	Low and large, yet still someone who speaks in full sentences
Edge	Distortion 0.25, 40% mixed in	A dark grain, never a growl
Doubling	Chorus 0.4 times a second, 30% mix	A faint second voice, as if power hums under the words
Chamber	Reverb 20% mix, 1.8 s long	A stone room of modest size, so speech stays crisp

Sound in charge

Speak quietly and precisely. Absolute power has no need to be loud; pronounce every consonant.
Put the stress on verbs of command and let the end of the sentence fall away, as if the outcome were already decided.
Use formal, slightly old-fashioned phrasing: decrees, verdicts, bargains with a catch. Monologues suit it better than banter.
Sit a forearm's length back from the mic so the 1.8-second room is heard around you.

Evil, villain or demon?

The villain preset this is built on is a smooth, theatrical human. The evil voice goes lower, adds more grain and brings in the chorus, so it sounds less like an actor and more like a ruler nobody has seen. The demon goes further again: far deeper, with a huge reverb, and no longer a person at all. Use this one for dark lords in tabletop campaigns, game-master narration and strategy-game roleplay. The second clip stretches the reverb to 3.5 s at 35%, from a throne room; the third adds Whisper 30%, the threat said quietly.
