A Colossal String Event (CSE) is an event where, due to quantum fluctuations, a "wall" is made using energy.
This event takes place in a timeframe of 1 zeptosecond - 50 zeptosecond, which causes objects to get obliterated if they are in the way of a CSE.
CSEs are seperated into multiple groups.
|Class||Lower limit (ly)||Upper limit (ly)||Description|
|A||0||1||The smallest known CSEs lie here|
|+A||1||1,000||Very rare, usually found at the edge of The Omniverse.|
|A*||1,000||1,000,000||Rare, found only on the edge of The Box.|
|+A*||1,000,000||1,000,000,000||Extremely rare, found appear randomly.|
|B||1 billion||1 quintillion||Somewhat rare, mainly exist in verses.|
|D||1 quintillion||1 vigintillion||Mildly rare, first CSEs ever observed were D class|
|G||1 vigintillion||1 centillion||Common, found outside of voids.|
|W||1 centillion||googolplex||Rare, first ever CSE (C00001#) was W class.|
|X||googolplex||TREE(20)||Extremely rare, only found in voids.|
|OMEGA||TREE(20)||Ultra rare, only 31 ever observed.|
|VARTHETA||inaccesible cardinal||Hyper rare, only 1 was ever observed (HC10251/A37E#)|
|Lower limit||Upper limit||Description|
|AC||254 vigintillion ly||899 octovigintillion ly||97.6% of CSEs land in this category.|
|BAD||100 billion ly||200 billion ly||BAD CSEs are around the size of our universe, the reason for it's name is due to the ability for one to consume our own universe.|
|GOOD||1 mm||10 m||GOOD CSEs are called good, because their damage isn't large and often repaired quickly.|
|/+A*/||1 billion ly||1 trillion ly||Extention to the A classes.|
|/*A+/||1 trillion ly||1 quadrillion ly||Extention to the A classes.|
|T||1 lp||1 ym||The 2rd smallest class of CSEs.|
|TT||1 lp||Very few have been observed at this level.|
|U||0||U class stands for Unconfirmed.|
