Found one burried in my harddrive, there's a lot of lore in here that we didn't know at the time, some of which the Letters Page has subsequently revealed.
We got our first confimation that Proletariet's powers came from an Oblivion Shard, that the Scholar's stone was not created with one.
Iron Legacy fell through time when he was defeated by the "core timeline" heroes.
Absolute Zero produces "Kidney Stones" of waste, it is not pleasant.
Citizen Truth may be more important than we realised.
Christopher mentiosn in passing a Sentinels Copmuter game he would like (relevent right now!).
OblivAeon is not part of a race.
Some tidbits about "The Wager".
CON is a She.
