Kafay is a very strong kind of coffee from the country of
Halt's Coffee

Halt drinking kafay

Arrida. The Arridi get it on the Southwest Islands and ship it in to the harbour of Al Shabah, from where it is traded to Toscano. Many Toscans are therefore addicted to it, which the Toscan leaders already tried to stop by forbiding the trade in kafay. 

Rangers all love coffee, especially the thick, rich kafay made by the Arridi.
