Eszrah ap Niht is Gaunt's personal bodyguard and aide in the Tanith 1st Regiment. He is technically owned by his commanding officer after being 'given' to him by Eszrah's father and Nihtgane chieftain, Cynhed ap Niht, as a token of gratitude on Gereon. Eszrah, dubbed Ezrah Night by a number of his comrades, has since been 'domesticated' following his intergration into the Imperial Guard, including learning low Gothic and the ability to read. He still uses the partisan Wode and his reynbow weapon, however. He has personally saved Gaunt's life on no less than 9 occasions, and has accompanied him into battle on every field since coming into his possession. Eszrah and Mkoll discovered Gaunt during their daeda waeg against the Blood Pact on Jago.
