[quote=Sauron the Dark Lord]Terminal, from your words I get the idea that getting there is the easy part, getting out is harder, due to limitations forced upon engines by the dark nebula. But what if the FTL system work's seperately from the engines?[/quote]

From what I've been told of the Nebula and the Asphodel system, the nebula does not extend fully into the system proper due to Erebos' heliosphere, which keeps interstellar media (like any good heliosphere should) out of the system. Trace elements still filter in of course, and functionally these traces impose a significant barrier to FTL. I couldn't provide you with an exact mechanism, but to provide some context, both the EOA's wormhole matrix and the Vazri Swarm's 'anything we can steal from other people' cannot function within the nebula, or transit directly into it (this is at the behest of the writers for Asphodel). So not only can FTL not be used within the Nebula, but they can't be used to go inside it either. I'm unsure if the attempt would be like ramming into a physical obstruction or more like an unexpected strain on whatever FTL system is being used, but I hadn't intended to press the issue. So if you want to enter the nebula, you'd have to stop at its boundaries and continue at sublight velocities - and to answer your question, that would mean it wouldn't matter if the FTL was separate from the engines. Additionally, the nebula doesn't appear to appreciably (results may vary) impact the functionality of sublight engines.

However, if you have an idea or argument as to why your/a particular form of FTL would work, I would contact a member of the Asphodel crew (Riemann, REDSHEILD, Druby, MissingAxis) and ask them about it.

As a chemist, I'd go as far to say as you don't know the exact specifications of beyond it's physical composition and the addendum of whatever hi-fi you added to isolate your nation. Nebulae, even dense nebulae that are so inappropriately named (), are not immune to radio waves or waves that are beyond the standard spectrum: X-Rays, Gamma, Infrared.The Graal would have no trouble identifying the presence of thermonuclear heat signatures planetside or the abundance of low frequency radio waves on the planet, this is technology Humanity in the 21st century possess. I won't press the issue however. LOL.

I am aware that dark nebulae are not as insulating as most people might think. However, this particular nebula is, as indicated above, somewhat unusual. It's been stated multiple times that it is very much a 'cold background' - any energy-intensive emission directly outside of it would stand out on sensors like a lighthouse beacon, which implies that any particular thermal/heat/nuclear signatures from inside the nebula are being masked, distorted, dampened, take your pick.

If one still posits that radiowaves would make it through, I have to cede the point. A potential excuse could be made by the point that the nebula is directly adjacent to another, much larger dark nebula (occupied by the Synchronicity), emitting radiowaves that are much more numerous. I am unsure if their nebula has similar properties (its proximity would infer so; the Erebos nebula may likely have split off from the larger Synchronicity nebula), but if you compared them on sensors side by side they would likely appear to be identical in terms of emission/output, skewed in magnitude towards the synchronicity. If you don't go out of your way to compare them side by side, any emissions escaping from the Erebos nebula could potentially be mistaken or masked by emissions from the Synchronicity nebula - depending on your sensors.

Either way, I believe it is the intent of the Asphodel writers to focus on their nation in the past, and to keep it off-the-grid in the present until those events have concluded. 

If you really want to scout the system regardless, by all means - the Graal Hegemony will do what it will do. You may be left hanging indefinitely on that end if you choose to do so however.
