Truculent Roper

A leader of the Workers' Cooperatives. He threatens Bucket not long after his candidacy is announced, trying to pressure him not to advance gnome interests at the expense of human workers. This backfires.
Minions include Silent Rock and Talker Tree (rumbling voice, breathes heavily), two very large men. He is himself large (though not as large as them), with a paunch. Some grey at the sides of his hair, above the ears, and in his thick but neatly-shaped beard. Looks like he doesn't smile much.
Son Rock Roper.
His real name is not Truculent; it's a joke that's become general, because of his aggressiveness and bad temper.
