True, but it might be something easily acquired by us. Purchaseable in Sigil, controlled by a former trade partner of Su'ryuu, or created by the Court of Stars, that sort of thing.
Isida - It looks like we are splitting up momentarily. Rahveon and possibly Caira are off to the Court of the Stars, I'm off to Sigil in pursuit of the people you gave me in my bardic knowledge result a while back, and Sigrun and possibly Solarion are going to attempt to grow our little nest egg of a plane. I'm betting that Su'ryuu also has something in mind (visiting Tiamat? former off-plane allies or trading partners? straight to Baator?).
How do you want to handle this? Will we be going through these simultaneously and in parallel, or do you just want to summarize the results of our efforts in a single long post, after we give some idea of what we intend to do? Either (or something else entirely) is fine by me.
