Can't find Knight armor at Ventari

Hi,
I am at ventari's refuge now, but I don't see the Knight armor set. Is it because I am still level 16?

Its not there anymore, you have to make it past the dragons lair to get the end-game armor now.

Knight's armor isn't available at Ventari's any longer. The soonest you'll come across it is with the Soldier's set (same graphics, same bonuses, same crafting materials, just a different name for the lower levels like Ringmail->Chainmail->Platemail or Wyvern->Dragon) in Amnoon Oasis. The Knight's set should be available at Roknar's Forge, perhaps earlier, in either Granite Citadel or Marhan's Grotto - but I'm not certain asI haven't made it to those places myself yet.

thank you for your help!
