this has been nagging at me.
a) we know that it takes place after time spiral because new type planswalkers are there.
b) We know it take place after shards of alara because ajani goldmane is older than ajani vengeant.
c) We know zendikar takes place after shards of alara because Sarkhan Vol has become Nicol Bolas' servant.
d) so it would seem that it takes place after Zendikar right? but chandra doesn't look any older in Lorwyn, does ajani age faster (cat years?)
e) also liliana cursed garuk and he seems to use black mana, and this happens during zandikar so the only way he could be totally green in lorwyn is if he was healed which has yet to happen.
I could just be nitpicking here but i think they sort of stumbeled on their own continuity.
