If you choose a sphere that is not covered by a current Imm, you are going to have a tougher time. Normally (I personally have only done it once), you would go about normally, Roleplay is your key. Occasional prayers asking for Empowerment, at the appropriate location, and then wait until a misc. Imm has time to work it for you. If you are looking for Galadriel's Tat, I would say you have just barely more than absolutley no chance. Basically she's dead, and unless her player decides to do something special for you, its very very hard.

Empowerment can be done, its just harder. Tattoo from a 'dead' goddess, virtually impossible. Though 'Galadriel' herself may want to chime in on your specific chances.

If you want Empowerment by a god that doesn't exist at all (You made up a Wisdom deity), you pretty much go the same route. Again its much harder, and you have to wait for an Imm. to have spare time to deal with you. I've only heard of one person ever getting a Tatt, from a non-existant god.
