Loosely inspired by the Plain of Jars, which was suspected to be used for cremation. Some local stories say that the King of giants used to brew and store large amounts of rice beer in them to celebrate his victory. If you ever decide to visit, be careful to not stray from the beaten track as there is a large amount of unexploded bombs from WW2 in that area.
Also. I realised much too late the human to jar size ratio. They’re supposed to be waaaaay bigger than what I drew. 😢
