"For this?! For this you would--"

Red light glows against her skin. Tattoos burn their way through her armor, patterns of jagged compass markings suddenly making themselves known through the glow as Saber grits her teeth in obvious pain. The look in her eyes is absolute betrayal. A moment later, they grow dull. 

Baleful light fades away, turning to smoke that rises from her body and sinks into her hair. Slowly at first, but then with increasing rapidity as it travels from the roots, her braid fades in color from striking straw to a dull, featureless gray. Not as a mark of age or veneration, but the kind of bland dust that all things turn to when their passion and vitality is forcibly pulled out of them and pointed somewhere it doesn't belong. 

The molotov bottle falls from her fingers and rolls along the ground until it rests under the front wheel of the Kun shrine. A shadow falls across her face as she rises once more to her full, towering height. It does not clear, even when she turns to behold the shrine again, knuckles gripped so tight around the hilt of her sword that they begin to whiten. 

"...Destroying this will bring her here?" she asks. 

Her back is turned to Diaofei. A cloak of shadows unfurls across her back, disguising the motion of her drawn weapon. Something halfway between a chuckle and a snarl escapes her throat that doesn't even resemble the voice of the king from just minutes ago and more closely calls to mind a wounded animal. 

Pain. Pain. Twisted pain and betrayal stacked high enough to climb the path between worlds.

"Then it burns."

She leaps into the air, leaving her Master behind to watch. No discussion, no planning, no strategy; her blade flashes like a torch against the queer lighting of Actia's hideout and then she falls as lightning, through the nest of cables, through the masks, and through the floor. Power crackles where she passes, sparks to start a fire. Her promise catches soon after, rising from the crater as she does.

Tiny, licking flames to start with. They'll build into an inferno before long, hot enough to melt even the outer plating of the steel giant watching over them. Saber stands and waits in the middle of it all, wrapped in gentle shadows that do not suffer a single wisp to touch her.
