Does "role" ever come up other than "this is what this tradition thinks about this spirit"?
And that nothing stops you from summoning "outside" that role.
As far as I know, you are correct: "role" is purely "flavor".
And, I've gone and looked at all of those non-Possession Logic traditions I listed before ... and they are REMARKABLY identical:
A: Fire, Air, Earth, Man, Water, _____, _____, ________, ________; Chaos
B: Fire, Air, Earth, Man, Water, _____, _____, ________, ________; Hermetic
C: ____, Air, Earth, ___, Water, Plant, Beast, ________, ________; Hindu
D: Fire, Air, Earth, ___, _____, Plant, _____, Guardian, ________; Islamic
E: Fire, Air, Earth, ___, Water, _____, _____, ________, Guidance; Gardnerian Wicca
F: Fire, ___, Earth, Man, Water, _____, _____, Guardian, ________; Zoroastrian
Seriously. There's only two that have something ONLY they offer - Hindu, which offers Beast spirits, and Gardnerian Wicca, which offers Guidance spirits. And even counting them, only two differ in more than one spirit.
