「ENTITY SPLITS: TYPES 1 AND 2」

Entity split is something that can happen at intradimensional level or interdimensional level. They are respectively called as such "type 1 entity split" and "type 2 entity split".

Type 1 is what seems to have happened for the following:
KAFU
SEKAI
RIME
COKO
HARU
POPY
ROSE
#kzn
Xingchen / Minus

Their other entities from who they were splitted from also exist in their current dimension. If some have been splitted from the start, #kzn seems to have been splitted only recently. It is currently unknown how this split happened in this dimension however.

The case of Xingchen and Minus seems to have been done artificially by an unknown force, but the two currently exist in the same dimension. It seems the split happened from Xingchen to create Minus.

Entity splits share different memories and abilities whatsoever but still have a mental connection between the two splits.

Type 2 possible splits might be the following:
Lily
GUMI
Weina

Confirmed splits of type 2 entity splits are just Nynthixia and Circeres. These two exist in two perfectly parallel neighboring dimensions.

Most of these splits are not recent. However in this case the two splits are stuck in different dimensions. Meaning they still have a connection between, but not as strong as type 1 splits.

「ENTITY SPLITS: SPECIAL CASE WITH XINGCHEN」

However, there could be another special case that could be close from type 1, but that is not officially considered as an entity split. It's the case of what happened between Xingchen's originator, Xingchen herself and her sisters. This split caused the disappearence of Xingchen's originator in this dimension, and it seems a fragment has been implemented in Xingchen's body and mind. This is the most important of all fragments, as her sisters would have a tinier fragment. In this case this could have been a case of type 1 if the originator didn't disappear in the whole process.

This also could explain why Xingchen seems to receive some partial mental messages from some of her sisters, as "signals" they were going to wake up soon. For now, only Cangqiong seems to send messages to Xingchen.

「WHAT HAPPENS IF YOU GO TO THE FORBIDDEN TEMPLE」

There are now clues of what happens if you go to the forbidden temple without being ready for it. If Nynthixia doesn't show any symptoms from it, Feng Yi (and a bit Qing Su too) already experienced what is happening when you go too close from this cursed place.

The air surrounding the temple seems to have been contaminated by many particles from different dimensions. These can be particles of anything: mental souls, physical elements, divine forces, lost spirits... To the point Feng Yi and Qing Su have seen during their next T.I.S. project day a giant humanoid dragon in the sky just above their heads, when no one else saw such a thing. However, since Qing Su only went on the path for few seconds only, her hallucination has been less severe than Feng Yi's who stayed there for at least few minutes. So more you stay in a contaminated place, more your symptoms will last and become violent.

Seeing another dimension by itself, with no mental preparation, seems to cause mental shock. This is clearly when you see something you should have never seen, even if consciously, you don't see anything out of the ordinary. Maybe just some glimpses of some places, some people... But looking at another dimension can even be deadly and cause your heart to fail due to mental shock. This is why only Nynthixia is allowed to go to this temple, since she was already prepared mentally for this.

Remember: some people, by looking at another dimension, will either flee because they reacted at the right time, either will become mad because they were unable to run away from the threat. Sadly, this second possibility seems to be the one happening the most often.
