Shadow Knight Thurgadin Armor (Velious Group Armor)
For the Shadow Knight Thurgadin Armor you'll need to collect Corroded Plate from Kael Drakkel, 3 gems from random velious enemies and bring it all to Dalgrim Underbelly in Thurgadin. Dalgrim Underbelly is found in the southeastern portion of central Thurgadin. Right after you go through the gate into the city from Great Divide hang a right and Dalgrim will be in the building to your right.
If you need further directions for reaching him I recommend using my map below. It has the location of every Thurgadin Class Quest NPC marked on it.

Also don't forget that these quests can be MQ (Multi Quested) as well! What I mean by that is, if your friend has one of the unmade pieces of armor he can turn that item into the NPC then you turn in just the gems and you'll get the completed reward.
This works differently depending on the server you play on. Those on the official Daybreak servers will have to be the same class as the person who is helping you MQ the armor. On the EQ emulator P99 any class can help you complete the multiquest.
Below this paragraph you'll find a list of all the different pieces of armor you can receive through these turn ins and the items required to obtain them. As aforementioned on the index page you'll need at least Kindly faction with the Coldain to complete any of these turn ins. If you need additional help raising your faction I'd recommend you complete the Giant Warrior Helmets quest.
