While discussing the issue of characters that are aligned with multiple realms in the other thread, a sudden curiosity (surely the proof that I have no life of speak of...) seized me. What happens of those mages that become true immortals ? Because, we know that mortal, if longeve, mages can have affiliations to more than one realm, but true immortality seems to involve getting a close alignment (getting a Might) with one realm only, typically Faerie or Magical. Then what would happen to a character that would have supernatural virtues from different realms, or a virtue that would get hermetic magic in tune with (an)other realm(s), too ?
I've tried to come up with a response:
Hermetic magic, of course, keeps working the same way, but actually becomes a vanilla magical or faerie power that mimics it, and may typically require spending might points for casting a spell. The same happens for Parma Magica, but the character has the option of using either it or Might MR. Since both MR and Parma are passive powers, and MR does not require spending Might points, so neither parma should.
Supernatural powers that exist in the new realm (e.g. Entrancement, Hex, Shapeshifting) got converted to the equivalent Faerie or Magic power. Powers that are specific to one realm (e.g. Sense Holiness & Unholiness, Divine or Infernal Methods and Powers) are simply lost. True Faith is a tricky issue, but I dubiously assume that wishing to become a magical or faerie immortal would mean lack of faith enough to disqualify one from it. AHowever, there are apperently God-blessed ways for a Divine magus to become a earthly immortal, see the Zoroastrian lesser immortality ritual (lesser as in, the character is still liable to Warping). The status of a true, hell-sworn diabolist is tricker still, and involves the thorny issue of whether magic or faerie powers are able to free one from a bond with Hell. I tentatively assume that in that case, the mage would become an Infernal immortal instead.
As it regards the Holy, Faerie and Chtonic Magic Virtues, they involve several different benefit that should be addressed separately. As for Holy Magic, I am tempted to treat it as the same case as True Faith. As it regards Faerie and Chtonic Magic, I'd say that the special R/D/T sets keep working (they are just an extension of Hermetic Magi) and so it does the ability to use faerie or infernal vis better (more of it) or more safely. Likewise, using charms or evil acts to power magic should work fine, as well, although continously doing evil acts for power might eventually taint the immortal toward the infernal, I guess.
As it regards aura bonuses and botches (immortals are immune to warping, so that issue is moot) I'm more uncertain. Tentatively I assume that all powers, including hermetic magic, should work strictly according to the Magical or Faerie aura interaction table. However, there is also the possibility that the immortal might keep a sympathetic bonus for the magic, faerie, or infernal auras, too... this depends IMO whether one places the affinity for a different realm's aura in the magus or in the magic. I mean, does the magic of a character with Faerie, Holy or Chtonic magic work as fine in the respective auras because of the character's alignment affinity for that realm -which is lost- or the magic's sympathetic affinity with that realm -which may be retained e.g. can the powers of an especially dark faerie work bettwer in infernal realms than the rest of his brethren ?
There is also the related issue of which kinds of immortals may still expend fatigue and which do not, and whether immortal magi can use Might points in place of fatigue to power spontaneous magic. Tentatively, I'd be favourable to answer yes to the latter question. Using fatigue to power magic -at least in the case of vanilla formuliac and spont and of virtues such as Life Boost and Life-linked Spont Magic- actually means spending a tiny bit of life-force, not physical exaustion, as the names of the above virtues indicate, so immortals should be able to substitute Might points for that kind of fatigue. As it regards rituals, they are more like physical exaustion, so immortals should be able to do them just without getting fatigued.
please give your insight. comments are welcome.
