Aetherius, a blade made of silvery steel, with gemstones embedded into it the color of deep night sapphire. The handle is wrapped with black leather strips, and the pommel has been crafted into the shape of two dragon heads. On the end of the handle, a long chain hangs, and attached to various parts of the chain are triangular charms, badges from the knight's travels.
Aetherius was a sword that Galaxii found in the early days of his knighthood. During an expedition, him and the group of knights he commanded were exploring a dungeon, purging it of creatures that could potentially pose a threat to the nearby kingdom they called home. He found this sword, by a forge that had gone many centuries without being lit. The group was then ambushed by a shadow beast in the darkness of the dungeon, and this sword saved Galaxii's life when the shadow beast pounced onto him and he held it between himself and the monster, piercing its chest. It's been his main weapon ever since.
He has no clue who made the weapon, as it was found in a dungeon long after its crafting, and he is unsure if it actually has any magical properties. But he does regard it with a bit of superstition, given that without it there is a very high probability that he would have died that day. The chain was something he added himself, as he likes collecting small mementos to remind him of his travels- not just badges, but any charms that he finds signifigant that he can attach and that will last being an accessory, he'll add it on.
