I found an Orcish-English dictionary, check it out:
Zorn (n.): deity of no real consequence or significance. Usage: Glab drekku ultharkt Zorn borkken (As the enemy prayed to Zorn, their pleas amounted to nothing)
As an aside, I’d certainly be glad to ignore this troop’s shortcomings if he was accompanied by the gift of changing Warlord class to an Orc and moving his home kingdom to Grosh’Nak.
