Changing the Mystcraft pages of a pre-existing age??

[FTB_Time]

I have a void world base and I have just discovered the 'Bright Light' Page, which would be very useful..

I doubt there is but I thought it might be worth a try - also perhaps there is a file in the world save which controls it which I could change?

birghtness is less useful than you think; it is essentially a permanent night vision buff while you are in the age

but no there is no way to legitimately change the descriptive book after the age is generated

With a magnum torch, no mobs would spawn?

there are other effects like plants not growing and such

The only way to change an age or to find out what symbols were added to an age is to do direct NBT editing. There is a DAT file for each age under \worldname\data\agedata_#.dat. Open that and you can see/possibly edit both the pages and symbols used. I haven't tried editing one myself yet so I can't say if it'll work for sure.
PROTIP: MAKE A BACKUP FIRST.
Also of note: The descriptive book contains no actual data about the Age itself, it's only a reference to it.

I managed to do it by creating another age with the new pages, and copying the old region folder into the save. - It worked!
