A few qns to ask:
1) Will they be able to enter Hall of Echoes
2) Can they communicate with the dead or possibly, even raise the dead(if circumstances are right)?
I suspect people will become suspicious or even terrified, once they find out you're a sentient skeleton. After all, you could be the Black Ring's lackey soo... might be hard to get around town.
So, I hope for some masquerading to do, as part of your disguise. :P Or at least some illusionary spells.
