I see that one of the included ships in Lure of the Expanse is equipped with a "warp-plotter" as a component. That's nice.

What's a warp-plotter?

Good question. Ask the devs, maybe they know.

From Sam Stewart:

"The warp plotter is a strange and inscrutable piece of Eldar technology. In game terms, it does not do anything, it's just part of making the Eldar ship run. If you need it to be something specific, it could potentially be something to help the Eldar navigate the webway."

So there you go! Thanks Sam!

Ooooh! Shiny, inscrutable Xenos tech. I feel like Gune from Titan A.E.

Gune: [holding up a small device] Does this look familiar? Do you know what it is? Neither do I. I made it last night in my sleep. Apparently I used Gindrogac. Highly unstable.
Preed: Gune...
Gune: I put at button on it. Yes. I wish to press it, but I'm not sure what will happen if I do.

I have decided that, in my campaign, the warp-plotter is a device which allows Eldar craft to find and use Webway portals without having to make Scrutiny + Detection rolls to locate them, and Pilot (Space Craft) + Manoeuvrability tests to pass through them. If the device is inactive, damaged or destroyed, the vessel must make these tests just as hapless Mon-Keigh vessels do.

Humans can't find webway gates all that easily; for the most part, humans don't even know the webway exists. Eldar vessels entering the webway are largely undetectable (compared to vessels entering the Warp). It isn't, as best as I figure, something that can be stumbled upon randomly by ignorant humans.

Perhaps not in your game, but I'm not playing in your game.

Anyway, I said nothing about "randomly stumbling"; a crew would have to know the portal is there to even begin searching for it. The portal in Lure of the Expanse is found automatically, so I'm being less generous than that.
