Dyson's Dodecahedron 1 8
Issue 8 of Dyson's Dodecahedron is dedicated to the Trouble at Imp Brücke - a sandbox-style adventure location for OSR characters of levels 6-7 (or so). It isn't so much an adventure as an adventure location infested with goblins well beyond their "appropriate" level¸ the dark heart of the stirges¸ and many¸ many cheeses!
All crammed into a 12-page digest-sized zine¸ and topped off with a random tattoo table for all your fantasy tribal inking needs.
