First off, Syrris sacrificed himself (soul and all) to save Polyphemus from himself. Poly was on the verge of losing control to his evil side, Syrris's act (done through an ancient shrine) fixed that problem. Of course, it also means Syrris is presently nonexistant.
Poly is planning to do the same now - he doesn't feel worthy of that, so once he beats Zorran (assuming he does), he's planning to trade himself to bring Syrris back.
The NDN is effectively disbanded, everyone's gone their own ways.
Tiderion is now considered a grand traitor to the guild - apart from behaving like a... (somethingnasty) to various people, including cheating on his mate, he also apparently has betrayed the guild in major ways (apparently feeding info to the enemy, at least).
Rommal is still attacking Roan...
The Veiled Mage has put in more appearances (few in person), and actually assisted Poly in figuring out how to use the shrine...
Roan still hates her thoroughly, Poly doesn't really anymore...
Kartania has more or less vanished from Furcadia...
Brinx returned last night and asked a fellow furre some questions. He then left soon after and returned this morning and met a furre named Vlady and wandered around some more before leaving again. He definitly will be back tonight.
