Are there..

[SAF]

....places to buy kanks, etc, in Allanak?

[Larrath]

The Allanaki Templarate is the largest seller of mounts in Allanak.
They have a stall in the Bazaar where they sell them...and though it's the Templarate doing the selling, I strongly recommend against going to a PC templar, or some other templar in the street, and asking to buy a kank.
There is a specific templar that sells them.

Heh heh.

That's something you need to find out IC.  However you can get a hint by reading 'help allanak map' (http://www.armageddon.org/cgi-bin/help_index/show_help?allanak_map)
