My first story.
I don't own Bionicle or any related trademarks, and am too lazy to sue for use of Xeon.
Dark Mirror dimension.
Xeon, Toa of magnetism, sat in his cell and looked around at the four stone walls, then down at his lean blue frame to the floor. He had disguised himself as a Toa of Water to hide his true identity and powers, even getting his mask in the shape of a Kaukau Nuva.
As one of the biggest open opponents to Tuyet's rule, he had been thrown down here, where he couldn't hurt anything. He was a master of magnetism and ex-leader of a resistance group, so he was a major threat to Tuyet's rule.

The surface
Takanuva tumbled out of a hole in space, an interdimensional portal. He looked around…

Xeon's cell
The Toa of Magnetism stared at the vortex in his cell. He triggered his Ivax, Mask of Information, which allowed him to get information on anything he looked at, and discovered it was a 'counterbalance portal'. Theoretically, it appeared whenever another portal dumped a being in the wrong dimension. He tried to get away, but could only go so far in his small cell. As he was sucked in, he wondered where he would land, then blacked out.

Metru Nui Archives, normal universe
"What do you think happened to him, Helryx?" asked Krakua. The two Toa, plus Brutaka, were studying what looked like a Toa of Water who had fallen out of a portal earlier. The being had a Kaukau Nuva-shaped Mask, two Scissor Staffs attached to his arms, and blue armor. "I don't know, but it looks like a portal of some sort." said Helryx. Suddenly, the being twitched and abruptly sat up. He gave the Toa a glance and put his hands in the air.
"Who are you?" asked the Water Toa. Xeon looked at them and put his hands down. They apparently didn't recognize him, and they had made no hostile moves. "Xeon, Toa of Magnetism." said Xeon. "Why are you here, and where did you come from?" asked the Toa of Sonics. "I don't know why I'm here, but I think I was brought here by him." responded Xeon, pointing at Brutaka and his Olmak. "And who are you?" he continued, looking at the Water Toa again. "I am Helryx, and this is Krakua and Brutaka." Helryx replied.
"So… where am I?" asked Xeon. "Metru Nui Archives." replied Helryx. "If you want information, visit the upper levels. Oh, and don't let anyone see you. No-one can know that we're here or that we possess an Olmak."

The upper levels of the Archives, 30 minutes later
Xeon was amazed at how different this Metru Nui was from his home. The events that had led to his creation and his becoming a Toa had never occurred. Tuyet was missing and presumed dead. And most importantly, Makuta Teridax had struck down Mata Nui. Xeon turned to Helryx."Is there some way I can help?" "No," said Helryx,"the Toa are in Karda Nui.""I don't have to work with them, is there anything I can help your team with?" "There is one thing," said Helryx.
