They are for the new cultural armors introduced with Dragons of Norrath (DoN) expansion.
Every race now has a cultural forge and new cultural sewing kits. The DoN armor is either smithed or tailored and has 3 augment slots:7, 11 & 12. The DoN augments go into slot 11 and you very much want these augments to complete the armor.
DoN armors can ONLY be made for the visible (graphically) slots: Wrist, Head, Arms, Legs, Feet, Hands, and Chest.
There are 4 tiers of armor based on required/recommended levels and level of tradeskill mastery:
tier req/rec level
Journeyman's 15/20
Expert's 35/40
Master's 55/60
Grandmaster's 65/70
You can also construct (via normal trade-containers) the augments. Augments are tiered as well.
