Bone Sword

The Bone Sword is a weapon created by Fern via a combination of bone carving, plastering, and his own power. It is fairly sharp and is usually depicted as being at least slightly large for a sword, as it is specifically designed for a dragon to wield.

Appearance
The Bone Sword is large and white, with a cleaver-like but slightly bent blade. It is said to be beautiful, and has patterns and runes carved into it.

In Season 1 of Adventures in Necrosis, it is depicted with a Dragon Slayer Sword, and thus has a black hilt and guard, and the blade is partially red; normally this does not occur. In other series, it is usually depicted using a Bone Cleaver from the Tinkers' Construct mod; this causes is blade to look straighter.

History
During his travels in Bornwish, Fern encountered a group of humans who intended to invade. Fern fatally wounded them, bringing their bodies to Bornwish to feed to other dragons he knew; he kept the bones, using his Nature's Breath to crate a vine-like plant that affixed them together; he carved them into the rough shape of a sword, and the carved-off 'shavings' were mixed with an adhesive originating from Bornwish, essentially making a bone 'plaster' that he used to fill in the gaps between the bones, ending up with a sword that appeared to be carved from one giant bone or fang.

Adventures in Necrosis
The Bone Sword was one of the few things Fern took with him when he left Bornwish to search for a place for Meadow to live in peace, and it served him well. It was his primary weapon throughout his journey through the place he would come to call Necrosis, and he kept using it until he encountered a knight named Gawain who Fern mistakenly believed would attack him and thus killed him; he briefly mourned Gawain's loss, noting he fought honorably, and took up his sword, which replaced the Bone Sword for the rest of that journey. Fern would later craft a stronger weapon out of Thaumium, but decided to keep using Gawain's sword for the time being, and switched back to the Bone Sword by the time he left; he used an enchantment table to enchant his bone sword with Fire Aspect II, making it stronger.
