Unfortunately I don't have access to my single-player save to get pictures, but I wanted to share the random Mystcraft age I generated:

• All the terrain is Packed Ice, in every biome.
• The age is in eternal night (as far as I can tell), so mobs spawn everywhere.
• There are lakes of Liquid Death all over the age - squids constantly spawn in them and immediately die, so occasionally essentia fragments get dumped on the shore.
• There's a star fissure right near the spawn point - great for emergency escapes.
• Mystcraft structures spawn fairly frequently, giving me plenty of free pages.
• There's a weird yellow liquid pool near the spawn that can't be picked up via bucket, and I have no clue what it is. Pretty sure it's not Liquid Yellorium, but I have no clue what it actually is.
• Even though it's a DW20 Mystcraft age - and iirc those tend to be ridiculously unstable anyway - the age appears to be mostly, if not completely, stable, with no random potion effects.

I've been using it to grind Ender Pearls (I'm in the mid-range of the tech tree, so I needed to get a few to get going), and it works out perfectly. Any suggestions for what I should do with the age, if anything?
