We have an entire zone dedicated to establishing that the fearsome Redguard warriors want nothing to do with undead and the absurd lengths they'll go to to avoid fighting or becoming undead, but when we go to Hew's Bane, we're confronted with these things:



What justification was there for these? I seem to recall it came up in an ESO Live, so I'm reasonably sure there is a justification, but I can't recall what it was. There's at least one in a legitimate modern Redguard tomb, we run into him during the Thieves Guild questline, so it isn't a case of rogue necromancers everywhere.
