I don't think you necessarily need to dial back the march of technology to account for magic, just as humans are experiencing magic for the first time this could be the Dralok's first real exposure to advanced 'mundane' technology. Just as humans are harnessing verse you could see Dralok slowly adopt modern firearms, etc etc. 

The easiest equalizer would to simply have much of who and what they are and what the're capable of obfuscated by rumor, as I imagine folk would be a touch superstitious after uncovering them. Just list a whole bunch of outlandish claims in the OP and be secretly aware of which ones are true and what's been omitted. 'I hear they can flow through the Verse' like blood through a vein! Billy swears he seen one snatch the life right out of old Auntie Snow.'. That sort of stuff.
