...“You… What are you doing here?” the Toa demanded, taking a step forward. The Toa of Ectoplasm before him, her armor battered, dented and burned in several places, merely crossed her arms and tilted her head down, still not looking at him. His eye twitched, and he clenched his fists. “You died on Gynel; no one saw you leave, and there’s no way that you could have survived the Brotherhood’s purge of the island. Either you’re smarter than I initially thought and found a way off without being killed or someone else had a part in it. Now answer me – how are you here!?”

...The Toa turned around, staring him straight in the eye, sparks meeting between those two pairs of glowing orbs -- one purple, the other icy blue. A sly smile was plastered upon her Mask of Psychometry. “I think you know the answer to that already,” she said coldly, raising her hand. Ectoplasm floated from it, swirling above her palm. “I’m as close to a ghost as any living being can be… and everyone knows that ghosts can’t die.”

A little spur of the moment piece. But what could it mean? Hm....
