I like that, My concern is that I will do something that people will say violates canon. I Have read up on most the literature on WHs and Sleepers, but I don't really know how much leway I have to write my own story.
Then just pose your observations as opinions or questions.
Example: The wreck seems to have Amarr markings of house Kador. Is that even possible in Wormhole space? I don't know a lot about Amarr Royal House identification or traditions, perhaps someone can help me out?
Example 2: My crew claims the Sleeper wreck is different from the standard sleep tech. I'm not a technician and I have some doubts about the skills of my crew. Can someone assist me in identifying the remains.
If you might not know a lot and/or are unsure, then simply play your character as someone with limited knowledge that is unsure.
Of course, if you're skilled at doing so, you can also play a very knowledgeable character while you as a player know very little, but if you can't pull that off IRL, better not try it when RP-ing.
