What does the immensely powerful being do?

I'm a fan of having a "somewhat powerful servant" of an "immensely powerful being" doing the asking. He need not be as powerful as the party, in general, but able to offer the party something they don't have or something they want. The "somewhat powerful servant" is too busy to handle the task personally and can't spare any resources from their own immediate agenda.
An "immensely powerful being" rarely hears about the failed attempts of its many "somewhat powerful servants" and only sometimes rewards the successes.
PCs and NPCS in game almost never have contact with an actual "immensely powerful being" and if they do, it is often a campaign ender (one way or another), so refusing a task can almost assuredly mean death (even as accepting the task can).
An "immensely powerful being" doesn't need a starship to get beyond the barrier. If he is tasking a group of adventurers it isn't because he can't do it himself, it is because he's not sure the group can do it and he thinks it will entertain him to find out.
