Taboos on eating and drinking
The mages seek to destroy the remnants of their food and drink when there is a danger they might fall in enemy hands, due to the sympathetic relation between them and their half consumed food.
Blood, Hair, nails etc tabooed
The mages destroy all products of their body when there is a danger they might fall in enemy hands.
Real Name tabooed
Most mages operate under pseudonyms and conceal their real names.
