This list is in more detail on one of the other pieces, but I thought I'd add it in breif to the rest. For more details, look at the Eldritch Collective Initiate Bracer, message name "drop" by "mikeagne".

page 1 from Galorin page 2 from Faeeron page 3 from Diloperia page 4 from Halorniop These pages give you the caster's book. According to another poster, the gnome camp is in Steamfont at -1160, -1760. They are all level 10, and do not agro. As I have not looked for them yet, I cannot confirm this. Just thought you'd like to know.
Yes the camp is in that location, BUT, they are higher than lvl 10 (more like 15-20) and DO aggro, touch one and you have a couple warriors, sdk, necro, cleric, etc all comming for you. Not pretty, I have tried it with one of my lower toons, but i always end up farming the no drops with my 52cleric, pull all, one aoe, all dead, log over, rince repeat. Nice item for 5 min worth of work on that book though.
