Alright, this is just to get you situated with how The Infinite Loops actually work. Loop mechanics (general): One person in a Loop, often the main character, is an Anchor. They are the person who first starts time looping. There is always at least one Anchor present in a given Time Loop snippet, though it may not be the local one. The standard pattern for a Loop is that the Anchor (and whoever else is Looping there) come to awareness in a loop at a particular point in the story. From there, events will play out as influenced by the Loopers present, acting with the benefit of their foreknowledge, until either a predetermined end point is reached or all the Loopers have copped it. To be Awake is to be aware of the Time Loops (that is, to have gone back in time this time.) The Anchor is the only character guaranteed to be Awake. Even after others have started Looping, it is mostly random as to whether they will be Awake this particular Loop. Crossovers, fusions, and alternate pasts can also take place. It is perfectly possible, for example, to have the characters Awaken into a Loop which conforms to a fanfic universe rather than reality. Loops do not have to be in chronological order, but it is strongly preferred that they not require a mutually contradictory order (where A must be before B and B must be before A.) Just about every Looper is very, very stir crazy. Tvtropes page: http://tvtropes.org/pmwiki/pmwiki.php/Fanfic/TheInfiniteLoops Threats to Yggdrasil: These are grouped by their ability to cause metaphysical instability in Loops or Loopers. Physical might has little bearing on this scale. The physical destruction of a universe won't even cause the gods to blink so long as its metaphysical data remains intact. The rating system goes from 1-5 in descending order of severity. Category 1 - Capable of dealing critical damage to Yggdrasil's systems. This has happened once and the event resulted in the Loops themselves becoming necessary to keep the whole system from crashing. A great deal of Yggdrasil's remaining power, roughly 90% at least, is dedicated to ensuring there's not a second. Category 2 - Capable of completely destroying a branch of Yggdrasil's system (more commonly known as a Loop). A looper, particularly an Anchor, ascending to the divine level is the most well-known method to trigger a category 2 event. There have been two confirmed category 2 events. Madoka of the Puella Magica Loop was manipulated by her Looping familiar Kyuubey into causing the first by ascending to the divine level, and the second induced widespread secondary damage across all active Loops at the time in an event now referred to as the Crash, which also almost completely destabilized the Mega Man Multiverse. Much of what Yggdrasil operators do is meant to prevent potential category 2 events. Category 3 - Capable of inducing metaphysical instability. Whether Loop or Looper, metaphysical instability is bad and, left unchecked, could worsen to a full-blown category 2 event. Yggdrasil operators have been known to intervene in category 3 events to prevent them from so worsening. Category 4 - Serious threat in-universe. Basically anything an experienced or veteran Looper could have significant trouble dealing with. A number of category 4 events result in universal destruction and/or the premature end of a Loop iteration. Little chance of causing serious metaphysical instability, so they're rather low on Yggdrasil's long list of priorities right now. Loopers are officially on their own dealing with these things. Category 5 - Standard competent villain level threat, and not even a blip on Yggdrasil's radar at this point. Generally a negligible threat to an experienced Looper. MLE - Malicious Looping Entity. Exactly what it says on the tin. An entity brought into the Infinite Time Loops by design or accident who either cares nothing for maintaining the stability of the multiverse, is actively working against it, or simply desires to use the Loops to bring harm to others (usually other Loopers). Anchor Candidates: Not every inhabitant of a universe is viable to use as an Anchor in the first place, much less after damage to their home universe is taken into account. Anchor candidates not chosen as an Anchor are also often among the first to begin looping. Here's a rundown of the categories of Anchor candidates that Yggdrasil considers when bringing a Loop online and how they correlate to works of fiction: Primary Anchor Candidates: The most likely beings to successfully Anchor a Loop and the first that Yggdrasil considers. These are the central protagonist(s) of a fictional work. Secondary Anchor Candidates: Somewhat less capable as an Anchor than the primaries, but still a decent choice if the primary candidates are too badly damaged to serve in this capacity. These are the major characters of a fictional work outside of the central protagonist(s). Tertiary Anchor Candidates: The least able to Anchor a Loop that are still in any way capable of doing so if both the primary and secondary candidates prove unviable for whatever reason. These are the significant supporting characters or frequently recurring characters of a fictional work. If all Anchor candidates prove insufficient to the task alone, then special measures like Linked Loops, 'jumpstart' attempts via fused Loops, or other special measures the Yggdrasil admins can code are initiated. If all of these fail, then the universe in question is typically set to Read-Only as a last resort. Note: It is possible for a universe, like the dreaded Eiken, to need no Anchor due to being stable enough to not need one. Read-Only: Basically, a universe is set to where nothing can affect its baseline whatsoever. No Loopers activate and no items native to this reality can be taken out of it. It's a last-resort measure and essentially the reverse situation from a universe stable enough not to need an Anchor. Skaia Protocol (Homestuck): A very potentially dangerous universe generation protocol using what seems to be portions (or more) of Yggdrasil's own universe generation protocols. Possibly a manifestation or copy - partial or otherwise - of whatever subroutines allow Yggdrasil to 'grow'. The good news is that all of the universes generated by the protocol were undamaged enough that they could be stabilized without needing Anchors, even if that would have been the easier option in some cases. The bad news is that universes generated by the protocol tend to 'drift' which means that the Yggdrasil operators can't quite get it locked down completely and thus sometimes have to deal with Loopers who encounter it. The gods closely monitor any contact with the Skaia protocol and will readily confiscate anything dangerous to the Loops.
