Sizeable Perimeter Reservoir
Found in: C1C2C3C4 C Single-source / unverified Class band stated by the EVE University wiki only - no second source carries per-class spawn data for this site type.
Wormhole fullerite gas site. Undefended when you land: Sleeper defenders arrive on a timer, so the pattern is huff until the rats show, then fight or reship. Fullerenes feed Tech 3 and capital production, which is why the deeper reservoirs are worth the risk. Classes it spawns in are listed above.

- Gas value
- 136,845,840 ISK (136.8M)
- Blue loot (defenders)
- 2,400,000 ISK (2.4M)
Two separate payouts. The gas in the site is the reason to come: ~137M ISK at the sheet's live prices. Killing the Sleeper defenders drops a further ~2.4M ISK in blue loot. Recheck prices before planning income, they move; the manifest quantities are the stable part.
