后室之钥是一种拥有能够通过门进入特定Level能力的特殊物品。
描述
A stash of Level Keys worth a veritable fortune.
后室之钥是在后室里很少见的物品。每个楼层都有自己的钥匙,可以有多个钥匙“属于”一个级别。大多数后室之钥与20世纪的铸铁钥匙相似,但它们也包含一个独有标识以表示它们的主关卡。它们可以在这些关卡内解锁门,也可以通过其他关卡的门进入其主关卡。后室之钥的功能与前室钥匙相同,但也有一些特殊之处。这些奇怪钥匙的许多内部工作机制尚不清楚,并且仍在由[[M.E.G.]进行研究
Properties
Interestingly, the most useful property of Level Keys is that they all resonate specific frequencies depending on how many Levels you must travel through in order to arrive at its 'home' Level. It is always the shortest route. Frequencies for each distance is seemingly random for each key type, however it has been theorised that if one could crack the 'prediction code' for a type of level key, one could predict distance based on frequency or vice versa for that key type. Datasets for level navigation far from the Quantum Stable levels are quite valuable and often sought after by expert explorers and wanderers. The M.E.G. has recently discovered that keys from the Frontrooms vibrate incredibly faintly, hinting at some sort of exit. If one could crack the prediction code for the Frontroom keys we could get a hot or cold detector that directs us towards the Frontrooms. This property is currently undergoing extensive research.
Level Keys used for LPSs (Level Positioning System) are broken down into shards for more compact storage and to maximise the amount of LPSs produced per Level Key. However, these shards are unable to open doors.
Small booklets are used in order to triangulate what level you are in. Here is an example from a basic dataset for the first twenty levels on how to utilise Level Keys to find your level location. A dataset is named based on the amount of keys it supports and the corresponding levels. For example a dataset named 5kLPS 0-10-20-30-40-50 means it supports up to five Level Key shards from Level 0, 10, etc…
Within the collapsible below is a step-by-step tutorial/scenario on how to effectively use a basic 3kLPS 0-10-20 to find your current level.
The most well known property of a Level Key however - and the main function of Level Keys themselves, are its ability to open locked doors within its home level and access its home level through opening the respective door within The Hub. Level Keys are inexplicably linked with their home levels, although to what extent we are unsure.
When held whilst asleep, Level Keys can occasionally induce strange dreams about many different levels, often random. It is assumed this is how {ACCESS DENIED} functions.
Locations
Level Keys are only found in their respective levels and are often hidden or hard to find, especially in large or infinite levels. They're considered rare items and are bartered for a high price amongst minor groups. Every level has their own Level Keys, though how many per level is currently unknown.
