I know ideas have been tossed around about what the functionallity of the hoard chamber should be... does it dynamically change, the more hoard your dragon gets, will it be like a "storage"
I suggest that the hoard be a place that players (bi-ped and dragon) could add to the lair-owner's hoard... as a donation for maybe supplying a needed machine near a popular resource.
I have given and received silver myself for my plot and it's "always open" policy and I have given to players that have provided needed machine near resources.
It is hard to catch them "on-line" sometimes, and I thought a "Tip-Box" type functionallity for Hoard lair chambers would be cool.
