: We do know that he didn't have them when we played the
: Great Library level, as he was hoping on using the
: Total Codex to find the Summoner. Unless of course, he
: needed it for some other reason, but we can probably
: safely assume he was after the whereabouts of the
: Summoner (after all, he was looking for him everywhere
: else).
17 days elapsed between The Great Library (when Soulblighter's army was thought to be small and easily destroyed) and Gate of Storms (when he actually showed up with Myrkridia.) It's entirely possible that he could have found the Summoner, started resurrecting Krids, and knocked off Andir before the inhabitants of that isolated village had even confirmed Soulblighter's return.
