The LotR mod has two Instagram pages used to showcase various visual aspects and new features of the mod. There was an old account that was active between 2014-2017 which has pictures on the Half-Trolls, Dwarves, chisel carvings, and older features. It has been inactive for a long time, and it has been confirmed that access to this account was lost. You can find it here.
On the 12th June 2021, a new account was made, which can be found here.
