The Grand Bastion consists of "The Grand Bastion Covenant" Faction and has three notable fighting forces:
The Bastion's enforcers of order and peace within - not seeing much real combat. Consisting of teenagers serving their mandated time in the Watch.
Despite them being draftees, they are formidable warriors and are well equipped - although in real combat they lack coordination and tactics.
The Bastion's main defense force, made up of highly skiled warriors with very high quality equipment and practiced tactics for any scenario - instead of being scattered around the city they man the walls and take care of any threats scaling the walls.
The Bastion's expedition force, made up of veteran Iron Legion soldiers, travelling far out into the Ashen Wastes to collect valuable resources that can't be found anywhere else - using some of them to commision their own gear. They are masters of open field combat and shock troop tactics, fighting in loose formations and brutaly breaking through lines of monsters and undead, with practiced ease and flawless coordination.
The Bastion's most elite defense force. They patrol and lurk in the tunnels beneath the city. They are masters of fighting in tight spaces and utilising the tunnels to encircle and ambush any threats that make their way into their domain. Carrying custom made armor and weapons they are by far the best warriors the city has to offer.
