Down the Chain

Class 4 wormholes

The quiet class. C4s connect to other wormholes and almost never to known space, so nothing casually stumbles through - safer to live in, and slower to move anything in or out of.

B Community-corroborated Two independent community datasets - anoik.is and the MIT-licensed whdbx dataset - agree on the static connections of 2556 of 2567 J-space systems (99.57%). Only the systems both sources agree on feed these figures. Aggregate shape only. Per-system statics are deliberately not published here: no official CCP source carries them, and shipping another project's table needs a licence answer first.

Class bands for gas sites come from the EVE University site list only. No second source publishes per-class spawn tables for this site type, so they render C Single-source / unverified . The combat, relic and data lists above are corroborated by the maintained Rykki guide B Community-corroborated .
