I think Scalenex means the underground sea that those Pesky Dark Elves keep using to attack Lustria.
If DE are going to be a threat to Klodorex, that presumably puts the Klods nearer the equator, but they also need to be within plausible distance of the Vampire Coast for Count Renliss' home range not to be ridiculously large.
Plausible geography and plausible storylines. That's where Scalenex went wrong and now he is stuck.
I am sorry my characters discarded that Arabyan Carpet they collected in Nehekhara (The one with ward save against everything except frenzied killing blow. Wait was that the shadow of a Ripper?).
I could have loaned the flying carpet to Scalenex and all his plausible problems would have just gone away!
