"I know not whom you may be, with the white skin of a thern and
the black hair of a red man; but were it only Thurid whose safety
were at stake you might pass, and welcome, in so far as we be
concerned.

"Tell us who you be, and what mission calls you to this unknown
world beneath the Valley Dor, then maybe we can see our way to let
you pass upon the errand which we should like to undertake would
our orders permit."

I was surprised that neither of them had recognized me, for I
thought that I was quite sufficiently well known either by personal
experience or reputation to every thern upon Barsoom as to make my
identity immediately apparent in any part of the planet. In fact,
I was the only white man upon Mars whose hair was black and whose
eyes were gray, with the exception of my son, Carthoris.

To reveal my identity might be to precipitate an attack, for every
thern upon Barsoom knew that to me they owed the fall of their
age-old spiritual supremacy. On the other hand my reputation as
a fighting man might be sufficient to pass me by these two were
their livers not of the right complexion to welcome a battle to
the death.

To be quite candid I did not attempt to delude myself with any such
sophistry, since I knew well that upon war-like Mars there are few
cowards, and that every man, whether prince, priest, or peasant,
glories in deadly strife. And so I gripped my long-sword the
tighter as I replied to Lakor.
