1.The Numenor ruins- i think these already spawn here but if not they should.
2.Large Numenor ruins all these are is just a bigger version of the current numenor ruins (the Numenorions were rich people) these would be quite rare and contain chests with the same loot as dunedain towers.
3.Numenor Ruined tower same as dunedain towers but made out of vanila stone bricks or numenor bricks (if those are ever added). these would spawn as rarely as large numenor ruins.
4.Numenor Lord House SUPER RARE (only two per world) would spawn loot: ten armour stands all have (vanilla) iron armour the floor would have red carpet and in the backroom it would have numenor lord armour (below)
5.Numenor lord armour- same protection as dwarven and parts of it would have mithril trimmed and a Diamond in the middle (note: only two per world)
last thing:mithril should be way more rare as the numenorions would have mined it out same go for althes....
DONE :)
