|Appearances||The Beginners Cave|
The Beginners Cave introduces Heinrich as a potential ally, located in one of the cave's early side-rooms. The adventure describes him as, "a human warrior... armed with a longsword and carrying a shield. On his shield is a sticker which says, 'Hi, I'm Heinrich!'" He possesses a hardiness of 15, agility of 7, courage of 105, and friendliness of 170. His weapon, a poor-quality Marcos sword, deals 1d8 damage. (The Heinrich in the Enhanced Beginner's Cave is identical.)
The character reappears in Tom Zuchowski's Eamon v7.0 Demo Adventure, chained to a wall in a dingy cell. Once freed, the game describes him as, "your old buddy Heinrich whom you have not seen for quite a while. He is a little worse for wear, but is OK." Heinrich also appears as an ally in The Castle of Count Fuey.
In A Vacation in Europe, author David Smith reveals that Heinrich — "an acquaintance of yours from an earlier adventure" — has died and bequeathed the adventurer some money. Remembering that Heinrich "always talked about going back to Europe," the adventurer decides it would be fitting to spend the windfall on a European vacation.
Heinrich has an unnamed brother who features in The Caves of Eamon Bluff.
Heinrich's sticker-decorated shield can be found in the forest in Escape from Mansi Island.
- A nearly identical character named Helfrick appears in Michael Penner's brief Test Adventure for Eamon CS. A sticker on his shield reads, "Hi, I'm Helfrick!"
- In the SwordThrust world of Diurla, the weapons vendor (equivalent to Marcos Cavielli in Eamon) is named Heinrich.
