your new quest is to mine some garnets. pretty much the same process as doing ore, so no big surprises.
first step is to find the gem field, between the ore and the sandstone fields. select a garnet node, equip your dragon quarrying ability, and hack away until you have the 35 pieces of uncut garnet you need for your current quest.
if you haven't noticed already, sometimes you get bonus resources, usually the next highest resource of the same type. or, especially at low levels, other resources you don't need at the moment will clog your pack, taking up valuable inventory space. therefore, you will soon become familiar with deleting unwanted items (followed shortly by the pain of deleting the wrong thing). it's another familiar process - select the item you want to delete, right click and choose 'delete [item]'. the confirm screen comes up - just click the 'delete' button to get rid of the desired items. remember - this is permanent delete - many a noob has cried rivers of tears after deleting a cargo disk and being told there is no way to get it back.......
as with the metal ore, once you have what you need for the current quest, your journal will update with instructions to return to jemenoth. speaking to the dragon crafter will get you a new form to scribe and a new task to complete. scribe the gem form as required and check your quest journal for specifics.
head into the craft cave, turn left and go past the smelter into the green cave. inside this cave, you will find the gem cutter workstation. use it and your dragon gemworking ability to make your 6 cut garnets. of
of course, your journal will update, advising you to return to jemenoth for further instructions.
and jemenoth will have you next create your first piece of equipment!! no spoilers, you will just have to come back soon to find out!
