Of course, in true Mandalorian fashion, the peace of these last few days is quickly interrupted by warfare. Not one to simply give up despite their recent losses The Empire launches an all-out assault against the Mandalorian systems the next morning.
Sabine and Ezra are awakened early the next morning by the sound of air raid sirens followed up by the loud click as the compound diverts all its power to defensive shields and weapons. Together the pair quickly scramble into their freshly painted armour before donning winter camp cloaks over the top and grabbing for their weapons.
One dressed both Sabine and Ezra run towards the command centre located at the base of the stronghold deep beneath the mountain. As soon as they enter the room they're met by the mass of organised chaos. Around them those of Clans Wren, Onyo, and Kryze, not manning the outer defences struggle to get a fix on exactly what they're facing. On the board behind them, a display shows no fewer than half a dozen star destroyers hovering over Krownest as the readouts follow wave after wave of Viridian energy cascading down to fall on the strongholds immense shield.
In the middle of it all however stands Ursa, an island of calm in the swirling storm around them. They wait several moments as she seems to focus on everything at once before she looks to Sabine and Ezra saying, "we have reports that the empire has landed walkers out beyond our southern perimeter, the terrain should slow them but it won't last for long. If they manage to get up here there is little, we can do to stop them, I need you both to take a team and neutralise those walkers."
Ezra and Sabine look at each other concerned at the thought of what they face before they both turn and make their way toward the southern end of the stronghold. As they make their way, they gradually pick up a small number of Mandolorians in camouflage gear before heading out to the wilderness.
Once outside however, they are brought up short, beyond the fortifications that have seemingly emerged from nowhere now manned by a literal army of the galaxy's most skilled warrior the world itself is lit in a Viridian glow as the energy from above impacts against the shield, the very air around them becoming more and more charged with electricity until it eventually discharges in massive lightning strikes to the periodical grounding stations.
Knowing that time is short they continue on their way headed south, travelling through the small single person passageways that Clan Wren has cut into the mountainside for just this occasion. Eventually, they reach the outer edge of the shield barrier and what they see brings them up short. There in the narrow passage below leading up toward the mountain stronghold advance 12 AT-AT walkers two abreast. They watch as they trample everything in their path, the destruction behind them leaving a clear path for what will undoubtedly be a full invasion force.
Ezra and Sabine look to each other seeming to have an entire conversation without words, until eventually, Sabine nods and Ezra kneels down in the snow as if beginning to meditate. Sabine turns to the others and then in a voice brooking no argument she says, "defensive positions, we need to hold this spot while Ezra works."
The others nod and immediately move about getting set up to repel Stormtroopers. Sabine watches for a moment before leaning down and pressing a kiss against Ezra's cheek and turning to join the others.
Several minutes later the others start to realise just what it is that the Jedi has planned. In the valley below the mountainside itself seems to begin to shake. In the distance, the periodical lightning strikes have stopped and above them, the air itself has started to swirl into the beginnings of a maelstrom. The imperials are no less quick to catch on to what is happening, already warned if the possibility of a force wielder on the planet they quickly disembark the stormtroopers from the AT-ATs and march on the centre of the gathering storm.
The stormtroopers march through the shield in tight ranks constrained by the shape of the passage and forced to charge head-on into the waves of fire that await them. Despite this though no matter how many Sabine and the others shoot down more keep coming. For every Stormtrooper that falls his comrade takes his place, stepping over the shattered bodies and Plasteel as they move steadily closer and closer to their objective.
Soon the storm gains even more strength as the winds begin to whip larger and larger stones into the air slamming into whatever is in their path. The Mandolorians for their part remain protected, but for many of the stormtroopers they aren't so lucky. Instead, they are repeatedly bashed and beaten as the stones slip between the cracks in their poorly made armour, breaking bones and rupturing internal organs. In their desperation some even try using missiles and thermal detonators however these are quickly swept away, their energy joining the already building storm.
Eventually however, the AT-ATs reach the edge of the shield barrier and begin to pass through. It is at this point that Ezra's eyes snap open, in the briefest moments between when the AT-AT clears the shield and when it fires on them Ezra releases all the built-up energy, the force moving down toward the imperials in an unavoidable torrent of energy that spells destruction. However, in that last moment as the energy races toward them, the AT-AT pilot fires and red-hot plasma launches itself toward the cliff face where Ezra sits kneeled, collapsing the cliff and pulling both it and him into the ruined passageway below.
