Greetings, The main points of this suggestion are the changes to the Dwarven door, listed immedietely below, and the Community chest, everything else is just extra thoughts.
Dwarven doors, the ones that are only revealed by moonlight, need some changes.
1. You should be able to set a password to the door, and thus it should otherwise be locked, or have the ability to be.
2. They should not open unless illumined. (Edit: only for the ithildin variant, so players can still have hidden doors inside mountains, etc)
3. They should ignore claimed territory, that is, be able to be opened by those not on/under banner protection, but not destroyed.
Community Chest
A chest that completely ignores banner protection.
It could be made by putting gold nugget(s) with a chest, and could have a gold leaf(or something) on it's top.
Reasons for these items:
Let's say you wanted to have a pass through your mountain, that you didn't mind others knowing about (Moria, duh). Maybe you want it for roleplaying features. Maybe you want it for hiding treasures, for others to find, but you don't want them simply mining around, or building dirt paths over obstacles/puzzles, and they get to the chest...and it can't open under banner protection, unless it's a chest that ignores banner protection.
Allowing faction leaders to put out weaponry, food, armor, etc in their keep, or any protected place, and not have to worry about the walls being lifted.
Allow faction members to drop off mined blocks for the faction.
Allowing faction members to have a workable room in the keep/hall/fortress, and not have to worry about a green-horn,disgruntled member,etc going on a griefing spree. It would also need a way of setting the chest so that only 1 person can open it (that is,for this particular point.)
Other items that could be useful to make banner-defying variants :
Forge(Elven,dwarven, normal,etc)
Normal Door
Anvil
Crafting tables (maybe this one is already independent, can't remember, if it isn't i don't see why it would need a variant, just make them independent)
Millstone
As always, sorry if this has been suggested before.
Thank you very much
P.S I hope this rearranging of the post is more satifactory
