The desert of isis

The Bard says:

The Desert of Isis, yes I know of it,
but not where.  My friend at the
University took a keen interest in
Cantellia.  He would mention the area
from time to time in the books he read.

I never lended much credibility to it,
he was obsessed with what could be
considered a fantasy at best.  Myth and
legend is all it is, there has never
been any proof that Cantellia has ever
even existed, let alone the desert.

However, if you do wish to seek it out,
I would start with finding Cantellia
first.  Before you go though, a bit of
advice...

From what I remember my friend telling
me about it, it is not easy to find, it
is extremely well guarded and hidden.
It is also rumored that the desert is
only accessible once per day, and is a
one way trip.

If you do find it, you've been warned.
