[size=150]Guarding the accumulated treasures of the house[/size]
I imagine that seasons of work that went into the enchanted devices in the stores of Coeris are greater in number than the ones that went into making the defenses by a factor of 3 or more. I imagine that charged devices make up a great proportion of them (they would have been easy for the survivors of the schism war to create in the immediate aftermath). I also imagine that there is a great deal of vis in there.
The vis leads to a problem. Large amounts of vis can not be left in one place too long or it starts to do things. Therefore the vis needs to be moved regularly. Therefore I see the rooms where the treasures of coeris are stored to be a third full at maximum. The other two thirds of the rooms are empty, or perhaps it would be clearer to say that the rooms are all empty of vis at least two thirds of the time. (you could also argue that moving it around won't help and there will be problems anyway. I'm not saying this was worth publishing it's just what I thought about
By and large I imagined the treasure to be protected by wards and enchanted items (sentinels and justiciars) just like the rooms in the sunken laboratory with the exceptions that
1 rather than having one or two each of sentilels and justiciars the store rooms have 5 or 6 sentinels and 3 or 4 justiciars.
2 rather than justiciars that do things to delay an intruder, like wrap a room in shrubbery or levitate the targets off of the floor, the justiciars in the store rooms have effects that kill things or render them harmless (perdo corpus spells that kill, perdo mentem spells that destroy minds, creo spells that do absurd amounts of damage and so on Also target room Demon’s eternal oblivion type spells against all four realms as charged devices scattered by the handful so several go off at once would be a common choice).
Now that I’ve seen the Richard's invisible assassin chapter in projects I’d imagine that there are devices that detect intangible tunnel style spells and dispel them. I was looking for a good way to do this when I was speculating on defenses but I wasn’t sure that I could.
Also the store rooms are filled with wood using charm of the herbam padlock enchanted devices as described in the chapter (they fill every available space within the room with solid wood). There are then intellego herbam devices that detect if there are any holes that develop in the wood and set off countermeasures (I never defined what).
The store rooms are kept in darkness to make scrying more difficult, I’d imagine at least one device that sets off the defenses if any light appears in a room with it.
Among the circular wards around the rooms is one that prevents to flow of any gasses.
One of the issues I had when doing my preposterously geeky calculations of what could happen if the treasure was disturbed without first removing the magical defenses was that a great deal of the defenses I wanted to institute would have destroyed certain types of vis or enchanted devices. But, if we keep the enchanted devices with the vis then only a third of the rooms have anything valuable in them.
Finally there is the issue of subterranean approach to the treasure vaults. I had imagined a whole bunch of buried enchanted devices forming a net beneath the ground that would set off an alarm if they heard anything at all.
A story hook is that the Tremere need to keep excellent records of the defenses so folks don't kill themselves when it is time to move the vis. What happens when these records get scryed upon. Are they in a cypher? is there an enchanted device necessary to view them - can it be duplicated?
