that letter was written by an Overlord of the Horde. he was no peon, so he could for sure buy some ink made of herbs or something. instead: blood and kodo poop
ok, we always knew orcs didn't exactly smell like flowers. but going as far as to use kodo poop as ink is too much.
what's next? devilsaur poop lipstick?
I didn't find the right solution from the Internet.
