Now Humakt's einheriar seem to get by without that requirement and yet join the immortal host of dead warriors. Zorak Zorani don't mind being zombiefied. Would Shargashi who died improperly behave this way?
Alternatively, the ghost of a Humakti (who, after Humakt's definition, is not an undead) might seek another body to occupy, only to cleanse himself of the improper death. Not as neat an encounter, but still a scenario hook...
