Long Read Indeed, But Great!
Before time the Elder Ogres were savage medieval warriours, that had nothing to do with guns and belong in earlier centuries. They were far more on the corner of the magic, that HellKnight attend. They were relative weak in weapons, but commenly strong shielded with their axes.
As the armour of the time quakers brought other skills like shells and nails, the ogres obtained these stronger weapons and became smaller. Guarded with their machine saws and grenades they've become a strange relick from elder time.
They lack technical skill and since they lost their shield
they only worry about grenades and cells.
