Lore
In certain marshes blessed by strange transmutative magic, a rare species of duck produces feathers coated in a naturally adhesive alchemical resin. When properly harvested (humanely, one hopes), refined, and woven into silvery strips, the result is the most powerful binding agent known to mortal tinkers.

Artificers swear by it. Clerics distrust it. Druids refuse to discuss it.

It is rumored that the first roll was discovered after a wizard tried to polymorph a goose into a rope.
