The Key of Nodoor is an Artefact given to Master Kitsune by Teen Kong upon gaining the Seat of Heaven in Yggdrasil.

The Key of Nodoor is an Artefact ooo with a single Hearthstone setting.

Game Mechanics
The Key of Nodoor can be attuned to for 3 motes. An attuned weilder can reroll 5s on Perception rolls made to notice or detect spirits and on Larceny rolls made to open or unlock something.

For 1 mote, the weilded can sense if there are spirit sanctums in the vicinity. This is a miscellaneous action. If a sanctum is present in the area (usually medium range, though some sanctums can be detected at greater or lesser ranges), the Key will glow, vibrate and audibly hum. The vibration and humming will grow in intensity as the wielder gets closer, until it shines brightly, its light revealing the location of the sanctum.

Once located, a sanctum's entrance can be opened. Spending one willpower, the wielder rolls (Charisma + Occult) as an extended roll with a Terminus of 5 and a goal number of 10 successes. Each roll is a miscellaneous action. The difficulty is determined by the Storyteller, with some sanctums being harder to breach than others (as a rule of thumb, the difficulty is equal to the spirit's Essence rating). If a spirit is physically present, he can reflexively attempt to resist. He opposes his (Charisma + Occult + Essence) to the weilder's roll each round instead of the standard difficulty.

Once opened, a sanctum will forever be accessible to the weilder fo the Key, without the need for further rolls, unless actively resisted by the resident spirit.

Failing to breach a sanctum by the terminus renders this particular sanctum immune to further attempts until Calibration has passed.

Celestial Hearthstone
Setting a Celestial Hearthstone in the socket of the Key of Nodoor increases its powers ten-fold. The Key will be able to sense sanctums up to one mile away and the wielder adds his Essence rating to his rolls when attempting to breach open a sanctum.
