True, Spirits 103:
Ritual magic does not depend on mana to function; it works
through the powers of the spirit world.
In 4E, T126's "Ritual Space and Mana" says mana modifiers MIGHT replace requirements for ritual space, which leaves the door open to stacking both penalties, making them super-hard.
Of course, that wouldn't mean their respective 'worlds' (although Shadow War seems like more of a distinctive world, Spirits is just more like a generic sourcebook?) would lack mana...
Voodoo 44:
If the GM and players decide to add “normal” magic to the campaign, it should
be very rare and hard to find.
In GURPS Magic terms, most of the world is a low-mana area, with pockets of no mana and a few small areas of normal mana.
S26 "The astral plane is a low-mana area"
S41: "Magical spirits may require mana constantly to exist"
S44: "At the GM’s option, spirits with Dependency (Mana) can be treated as “magical creatures.”
