This cross-section of a silver maple branch with a branch collar is a great stand-in for a downed massive tree. The piece is 3 inches long, 1.75 inches wide and 2 inches tall (76mm by 45mm by 51mm tall). This piece needs a stalking 4-legged predator, a blue alien huntress kneeling to shoot something in the distance, or just a bunch of grippli having a grand ol’ time. You could also cut a hanging notch or two along the flat edge and hang it directly on the wall.
These are currently unfinished rounds of silver maple. Some of the bark will have bits of lichen on them. The rounds are all roughly 1.25 inches around and a quarter inch thick (32mm round by 6mm tall). Perfect for your basic adventuring party; cleric, fighter, mage, rogue, and dwarf.
