After perma death you have to buy a new life spark, but with every pledge comes at least one. Sparks are separately for sale in the microshop . $25 each. Way to cheap, if you ask me :)
And with that spark you may continue your soul, which is already a little more developed than your soul was when you started your journey in Elyria. Don't forget that perma death is not easy to accomplish, unless you log out and come back after a year.
