That is entirely up to you. Honestly the CS ended up chunkier then I origionally planned for, given that there's basically 2: god and mortal forms.

The god form will pretty much never change as you said, whereas you may adapt the mortal form as needbe. If you like a particular incarnation alot (or don't want to mess with the CS every time, which honestly I don't blame you), you can keep as many details and tide them over as appropriate.

For example, in the next era after this one Rimguage's information will be pretty much the same, with some tweaking to his history and maybe appearance as appropriate, partly because the Tribal era will be quite short. In a later incarnation - probably around medieval times, I'm thinking? - I'm probably going to readjust alot of his appearance stuff. I think his personality shall stay pretty much the same, with minor tweaks here and there.

I'm glad you asked that!

Characters forget much between their lifetimes, as per their curse. [b]However,[/b] their soul is able to "remember" aspects of their various lives. Furthermore, they get better at using their powers in their mortal bodies (in their first incarnation, they are terrible at it and will die very quickly, fair warning. This is because they are used to using their powers without limit or problems. In later incarnations, they can use more powerful abilities without as much problems, as their souls become used to being a human)

Mechanically speaking, you can retain one memory or one skill between lifetimes (I'm currently deciding whether to alternate this or do both each time) This will allow the roleplay to progress without total futility, and the characters will get stronger over time,  eventually being able to break the curse, supposedly.
