How a Wild Magic weapon transformed my D&D campaign

When I first started as a Dungeon Master about a decade ago, I had a rigid plan for my Dungeons & Dragons group. I wanted them to join the ancient order of magical Weavers, under the tutelage of an Obi-Wan Kenobi-style veteran named Cid. Each of them would acquire their own Relic of Anur, a powerful artifact weapon made of an alien metal with transformative properties. The Ranger, Iona, got an arm that can transform into all sorts of things. The Artificer, Khatska, got a spear that changed in size and allowed her to teleport.
