I already know that if Phaedrus joins the game, he'll want it, so I'll just skip him.
I don't really care. When you're ruler of the world, it's
all your gold.
It's sure fun to have extra magical doodads, but if it makes it harder for you as a DM/you don't want it, then don't use it. (I typically use mine for Smoking and/or Warning armor spikes/etc...)
Debating who/what to play... Of course the
warlock puppet master I mentioned earlier could certainly fit, but so could some version of
this aboleth build I made a while back. I've made so many characters that I never got to play, it's going to be hard to choose... Hmm...
Edit: I might prefer this
aboleth/mind pirate build, actually. Of course, I'd get rid of the grafts for normal equipment. I'd also have to figure out how to refluff it to work in Eberron.
Edit2: Looks like Keith Baker already worked on
fluff for the aboleths in Eberron. The Mind Pirate abilities could just represent unique manifestations of aboleth powers, rather than being tied to the river Styx. Another suggested "conversion" I found was to say that the River Styx does exist, but is within Khyber, and represents the still flowing blood of the ancient progenitor dragon.
Or maybe just straight-up play a
Lord of Dust.
