Old School informed GURPS Dungeon Fantasy gaming. Basically killing owlbears and taking their stuff, but with 3d6.
Gimmie three orcs, gimmie three orcs mister, give me three orcs towards the door!
That's the verbal component to the magic-user spell Summon Orc 1/2.
I believe the lyric is "...give me three orcs towards Mordor!"
Orcs are Mordor-Americans, so that fits.
Black Tree Design?
Yeah, from their Harbringer line.
These look properly old-school!
