I know someone who struggles with that concept
Ha, yes I also struggled with the undead trumpeter concept for a long time! It was the Grenadier undead war mammoth, one of the riders was blowing a horn and it just ruined the whole mini for me.
Then someone (might have been on this forum, actually) politely asked why my suspension of disbelief was being shattered by
that, as opposed to all the silly metaphysics involved in the very idea of necromancy, and I got over it. Now I quite like skeleton trumpeters. I like the idea of them mindlessly trying to do what they did when they were alive.
