Hey, thanks for your edits. Its great to see another editor :)
Your timeline is a good start, but IMO its a bit too linear given that a bunch of things are sub-events of other events or eras. It also suggests that the only important history is that of vorinism.
The war in tranquiline halls will probably be left to the expulsion article rather than the halls article itself but its all up for discussion
I totally agree with you. Obviously there is a lot of information we haven't learned yet about the history of the world. Also, given that the war/expulsion/etc are a very Vorin view of the past it will be interesting to see what the other world religions (hopefully this will be revealed later on) view as the 'creation-myth' for life on Roshar, i.e. is it similar with different names or something else entirely. I especially imagine the Shin will have an interesting take on pre-rosharan history.
Also, I'm having trouble with the 'History of Roshar' given, as you state, that it is a very vorin focused timeline. Also, I totally agree that there should be 'sub-branches' of the timeline, for example, the war of reckoning needs (and has) it's own separate timeline. I just haven't decided on how I would like to link the two timelines together in the wiki. If you have any ideas, please let me know. --Shardslayer (talk) 14:08, 16 January 2015 (UTC)
