I was thinking that the addition of hoard chambers could be added without a terrible amount of changes.


By using the following in game resources;


Dragon mural –
Use existing building requirements for the murals


Stack and bulk;

Biped Cloth Tent -
max stacks 10
max bulk 1200




Displayed graphic -
Hoard chambers depicted in the Dralk and Chiconis vaults.


Those ugly blanks could be made to look atractive and functional.
