As she'd predicted, the enemy struck hard and fast.
It would take time for the Nerubians to arrive - she was counting on that fact. By the time they came to take the Keep, the living would be gone.
One thing at a time.
Arrows, geists, and gargoyles rained from the sky - the scrawny, lithe geists had chosen to scale the walls, to no appreciable success, while the gargoyles scouted from above, seeking any living targets and trying to drag her archers from their perches.
They didn't find much success in that plan.
Khary's arcanite-reinforced, ghost iron armored skeletons decimated the weaker undead that stormed the gates, while her ghouls worked together to dispatch any abominations she herself did not take care of. More than once, she was grateful for her own thick plate armor.
Sure, it wasn't saronite - she'd sworn never to use the foul metal again - but ghost iron, that enigmatic material that flooded the market during the war for Pandaria, was just as durable, and had already managed to save her life without ruining her sanity.
She began, slowly but surely, to lose forces. It began with a massive flesh golem. This thing didn't much care as it became a pincushion. It crushed her ghouls into a fine red paste, and ripped two of her armored skeletons limb from limb, before her 'people' managed to destroy it. Three gargoyles worked together to harry her archers, knocking them from the walls to crack apart on the ground so far below.
It would take more time and concentration than she had to raise the broken bodies to fight once more.
It was a little more than an hour into the heavy fighting. Though Khary herself hadn't taken any severe wounds, her armor was banged up pretty badly, and her forces were down to a single one-armed skeleton and her own self.
The ground rumbled beneath her.
The Nerubians had arrived, tunneling under the walls of the keep. There was nothing she could do about that - it was an eventuality.
The comms reported that the mages were going through their own portals now, unravelling the magic behind them.
The garrison was lost - but this day, the battle was won.
