If a mage were buried alive for whatever reason - whether deliberate as some part of a gambit of sorts or not so deliberately via accident or attack - does there exist any specific magic or uses of magic, that would allow them to survive buried and avoid what should be a rapid suffocation for an extended period of time?
I have a suspicion some skill with the Forces sphere with it's manipulation of elements might have potential on this front, but as a whole I'm not entirely certain.
Any disciplines and potential ways would do good for an answer to this question.
