I enjoyed the 08/03/2016 development log. I love that the tower's ruling demon got killed by an elephant, those legendary beasts still kick ass as they should! It's pretty exciting that nations can go to war over a family heirloom, after all the best causes of war are the most futile ones.
I'm looking forward to them having more reasons to want the item than "it's an artifact". I guess memories of the glorious ancestor are sufficient for the family of the maker or the namer of the object, and Kobolds just steal anything shiny, but to some races and monsters it could be considered as worthless junk or just a curious trinket (i.e. not worth going to war over).
Also, I don't remember whether groups can give in to demands to avoid war? I imagine the huge goblin army showing at your door demanding you surrender "ShieldBattered the Shiny of Shinies, a wood bracelet menacing with spikes of Adamantine" so the chief's wife can wear it. Then if you actually send someone out to give the bracelet, they might leave peacefully. (Or decapitate the bearer and laugh at you and proceed with the siege, if they feel particularly cruel.)
Which reminds me that parley and emissaries would be a particularly cool game mechanic ripe for tension and betrayal.
