Obsidian orb

Kōwhai's talisman is an obsidian orb he protects with his life, as it was given to him by someone he loved a great deal. He never let's it out of his sight, and those that know of it have heard him say it has "magical properties" he explains that the reasoning for this is because "In many stressful situatuons, I've held it and it's calmed me down, I've always been able to keep a level head with it close to me!" No one knows if it is indeed magical or if it's all in Kōwhai's head, and that the reason it keeps him calm is because of the memories tied to it of his loved one, and that it's a sentimental item. 

Either way, the obsidian orb has helped Kōwhai a lot on his journeys.
