Lord Commander Commissar Cassius Bloodtide
A mentat and expert on fighting the eldar
Commissar Bloodtide is a tactician with centuries of experience fighting the eldar, and more recently decades of experience loving one. He has been retired for a long time, but sporadically gets pulled back. He is unwilling to support the Imperium in simple fights over territory against the craftworld eldar, for the last 80 years or so he’s only agreed to fight the dark eldar.
