Then there's this :It represents the heart of the Shadowlands' military might. The souls here defend Shadowlands from external forces and wage war on the enemies of death
Is Shadowlands Hell ? They don't say the the cold confines of some specific Shadowlands zone but the whole area... where else other than Shadowlands can souls go ?
