Jonathor Quest
From Warhammer 40k - Lexicanum
Jonathor Quest is a Lord General of the Imperial Guard who defeated the dreaded Warboss Kodos in a valley sacred to the Imperium, despite being hopelessly outnumbered.[1a]
Later Colonel Ryn "Biffy" Drecker, who served under Quest, would try to imitate his success in his defense of the Cathedral of the Drowning Saint from the forces of Chaos, with disastrous results.[1b]
