Could I get some help on generally how long before the Odyssey storyline the Otarian Cabal was formed? There are some hints in the Legions book that it may be well more than a century (and thus before the time of the Phyrexian invasion and the apocalypse), but I have not read the Odyssey novel to confirm this. Can somebody please help out? Also, a secondary question to anybody who has read the novels Odyssey and onward: Is it ever mentioned who invented dementia summoning? This has to do with the fanfic I'm writing, and if the "facts" are presented in published novels (canonized), I just wanted to get the facts straight and not butcher the storyline. Thanks to anybody who can help me out.
