Quests
There are nine Alliance only quests, three shared quests and two Horde only quests.
Alliance quests
26 Tinkmaster Overspark - This is a quest to lead you to TinkerTown in Ironforge.
26 Save Techbot's Brain! - This quest is completed outside of the instance itself. On a side room off the pit that is straight ahead as you enter you will find Techbot. Techbot is a level 26 Elite mob. Kill him and take the necessary part.
27 The Day After - This quest leads you to the town of Kharanos at the base of the mountain near Ironforge. There you talk to Ozzie Togglevolt and obtain the Gnogaine quest. The reward is a minimal bit of XP.
27 Gnogaine - This quest is also completed outside of the instance. This one is a little tricky. You need to stand near a living Irradiated Invader or Irradiated Pillager and use the vial that you were supplied. Bring a friend to hold aggro while you do this.
30 Gyrodrillmatic Excavationators - The guts you need drop off of all sorts of mechanicals in Gnomeregan. You need 24 but these are very plentiful. The worst part is they take up two bag slot.
30 Essential Artificials - There are artificial extrapolators spread all around the lower layers of Gnomeregan. Click on one to get an item. You need 12!
30 Klockmort's Essentials Alliance - Another quest to send you to Tinkertown in Ironforge. They sure don't want you to miss going to Gnomeregan.
30 The Only Cure is More Green Glow - This is a follow on to Gnogaine. Same thing only you need to use the vial on green glowy mobs inside the instance.
30 Data Rescue - There are various (four/five?) punch card machines spread around the various levels of Gnomeregan. Click on the and don't forget to ask for an upgraded card. Question here: Do you need to have all the cards with you to turn the quest in? Or can you ditch them as you get higher level cards?
