Re: 2: If my lone (actually possibly one of two at this point) apparent past life dream is in fact that and I remember it correctly, then it is possible for even individuals at the human/human-equivalent level to bail from a world whose star is late in its life cycle to continue their development elsewhere - I'm a living example, my last incarnation lived on a planet orbiting a red giant/a star late in the process of becoming a red giant and was becoming uninhabitable as a result. If that's possible for my own soul, I assume something similar can happen for souls who aren't at the point of reincarnating into bodies at the human level of development.

(I'm not sure it's common, mind - I actually wouldn't be surprised if the advent of new divine sparks ceases before a planet becomes uninhabitable and the remaining souls of plants/animals/unicellular organisms are souls reincarnating in lower forms as the souls who are going to complete the evolution process basically evaporate off, either into Gwynfedd or by finding the gates between worlds, nor would I be surprised if the former is much more frequent. But it should be possible.)
