Yes, it simple by killing chickens and picking up their feathers they go for between  2-4 gp on a non-members world and 5-10 gp on a members world.

b) Rune essence running.!!

To do this you must complete the ‘rune mysteries quest’ it is fairly quick and very easy to do. It will tell you how to make runes and how to mine essence.  Once you can mine essence try and find the alters (see end for locations) stand out side and say “swapping essence for runes” most crafters will trade with you because they want the xp. If you are a member (if not I strongly recommend you become one as it opens up many other money making methods. See members money making section) logon to world 66 and travel to entrana where the law alter is located there are people there that trade you 27 laws and 27 noted essence when you trade them 27 un-noted essence.
