This is absolutely fascinating! Does anyone have any thoughts on it so far?
For everyone's record, I'll transcribe it here:
lmc1 - 125
Loadstone Mining Consortium #1 - January 26th JoJ (event on the 25th)
unkindness - 325
Prisoner brought forth - March 25th JoJ
lost will - 701
Darkwill Assassinated - July 01 JoJ
quarter egress - 703
Possibly refers to Noxus shipments in Zaun - July 22 JoJ (theories abound regarding Jarvan being held here) -OR- Dominion announcement (date off by one month, however) Quarter = Fourth = Jarvan. Could also mean this is when Jarvan was replaced by LeBlanc.
mirror play - 722
Jarvan attacking Swain - July 22 JoJ
quarter to clutter - 908
Future events involving the same thing referred to in quarter egress. Shipping Jarvan? Dominion launching? Jarvan coming back to the League in person?
Maybe the Ivory Ward, where DeCouteau vanished? Also, opals diffract light. Could be a reference to the Lightshields, maybe meeting at their mansion or somesuch?
Editing with what we believe to be correct!
lmc1 - 125: either Jan 25th or Dec 5th ([url2="http://na.leagueoflegends.com/story/issue-12-21-december-20-cle"]JoJ 12[/url2] or [url2="http://na.leagueoflegends.com/story/issue-14-26-january-21-cle"]JoJ 14[/url2])
unkindness - 325: March 25th ([url2="http://na.leagueoflegends.com/story/issue-18-25-march-21-cle"]JoJ 18[/url2])
lost will - 701: July 1st ([url2="http://na.leagueoflegends.com/story/issue-24-01-july-21-cle"]JoJ 24[/url2])
quarter egress - 703: July 3rd ([url2="http://na.leagueoflegends.com/story/issue-25-22-july-21-cle"]JoJ 25[/url2])
mirror play - 722: July 22([url2="http://na.leagueoflegends.com/story/issue-25-22-july-21-cle"]JoJ 25[/url2])
quarter to clutter - 908: September 8th ([url2="http://na.leagueoflegends.com/story/issue-5-14-september-20-cle"]JoJ 5[/url2])
The date each number could be, followed by the JoJ article right on the date or the next one after the date. Might help. At very least, exists as some form of making possible proof of theory easily accessible.
