Nebulae are an important strategic part of Ferion. Each nebula has a different function and can change the strategic choices players make in the area around them.
You will find them as gray clouds on the map. Once you fly to a nebula it will automatically be revealed what kind it is and what it does. Discovery happens slightly outside the effect radius, so you'll usually spot a nebula's identity before you enter its effects.

Each game places 10 nebulae in the largest empty areas between star clusters, well away from the galaxy edges. They never overlap, and their positions are fixed for the whole match.
Each nebula is seeded with one of 5 types. There are 10 nebulae total and 5 types, so on any given map some types may show up multiple times and others not at all. Each type has a stable signature colour so players can identify the effect on sight.

Hides ships inside from enemy scanners regardless of scanner range. Useful for staging surprise attacks or escaping pursuit.

Yields Ferros Nr.6 (level 3 alloy) once per week to ships parked inside that are fitted with a Nebular Harvester.

Yields Sjampoo (level 3 luminescent liquid) once per week to ships parked inside that are fitted with a Nebular Harvester.

Yields Texorrium (level 3 volatile compound) once per week to ships parked inside that are fitted with a Nebular Harvester.

Demilitarized zone. Attacks against any target (ship, planet, portal) are blocked while the attacker is inside, and ongoing battles pause if either side enters.
Every ship sitting in any nebula gets a weekly damage roll. We roll a d100 per ship; the result maps to a percentage of the ship's max hit points:
| d100 roll | Damage |
|---|---|
| 1 – 50 | 0% |
| 51 – 75 | 1% |
| 76 – 95 | 2% |
| 96 – 100 | 3% |
Damage has a floor of 1 HP whenever the roll lands above 0%, so even tiny hulls aren't immune. If a ship's HP would drop to or below zero it is destroyed. Players whose ships die that week receive a single aggregated "Ships lost in nebula" news item — one entry per player per week, regardless of how many ships were lost.
Three factors determine your weekly take:
No — only the final attack location matters. Passing through a Sanctuary nebula in transit is fine. If the target of the attack is inside the nebula (or if your ship is inside when the attack would resolve), then the attack is blocked.
