I'm not sure if this is the right place for this, but here goes...
I'm writing my first "serious"-ish campaign (one with proper lore and everything) and I've run across a problem. The PCs are high-tech-level space explorers making first contact with a low-tech-level planet and are stunned to find they are worshipped as gods. There are dark secrets behind this, of course, and plenty of space hijinks will ensue as they try to set the record straight.
On this planet, within the global religion, gods are not "nice". They are able to bring blessing, but they are just as willing to curse. They're capricious, they can be spiteful, and they really don't care about the lives of mere mortals in general. They're something like the Greek pantheon. My problem is this. How do native NPCs address my PCs?
"Your worship" and "Your holiness" immediately sprang to mind, but those already have different meanings. "Lord" or "Master" sound too generic, and "Father" or similar Christian-like honorifics don't really fit with the image of a god who has no fatherly feeling towards his worshippers. The PCs don't look like any particular gods the NPCs know, and are identified as gods based solely on their starship, technology, and strange uniforms, so the NPCs can't just give them names from their recorded pantheon.
