I am the eternal newbie....nebulas... a ?

[dogscoff]

Are you confusing nebulas and storms?

A nebula is a cloud that takes up an entire system. A storm just takes up one sector. They can both be destroyed but they require differnt components. Can't remember what they're called but the storm creator is early in the stellar manip tree and the nebula destroyer is toward the end.

Apologies if you knew all this already...
