Years passed during which the Toa Metru battled with the Morbuzakh, imprisoned Makuta, managed to defeat Sidorahk, Roodahka and the Visorak hordes and finally relocate the matoran to the Island of Mata Nui.
Then they awoke them, becoming Turaga in the process before helping the matoran to make a new life on the island while they awaited the arrival of the Toa Mata.
Eventually Takanuva was revealed and fought with Makuta, during which they became Takutanuva who raised the gateway to Metru Nui and revived Jaller.
The Turaga were quietly delighted to be able to inform the matoran of where they'd originally come from.
Then as they prepared to return Sherrie and Wotzit appeared for the first time and a kraata was revealed to be more than she appeared.
Several more years passed in which the human and her dog returned to the Bionicle world before Sherrie/Anuenue's destiny was fully revealed and Kokua joined the Toas' ranks.
The rebuilding of Metru Nui went steadily with a pause when the Toa went seeking Kokua and found they had to locate the Mask of Life, which could heal the Great Spirit.
Returning to Metru Nui with the Voya Nuians, Toa Voya and one of the Order of Mata Nui when Voya Nui ripped itself apart.
After a brief quiet spell then came Aikane's abduction and rescue followed six months later by the entering into legend of the seven elder Turaga.(1)
All this time Rionna slept in the sphere.
The healing draught she'd taken slowed down by the effects of the sphere and it had somehow managed to protect some of her memories of after the fever had first broken.
While the calf played with the young Kikanalo, the chief gazed around the landscape until he found what he was looking for.
*I think it's think we tell the tall ones what happened before the dark time* he rumbled as the rest of the herd finished eating and moved to join him.
Soft growls of agreement came from the others, then as they turned to head for Keetongu's cavern the calf glanced back then slipped from his dam's side for a better look.
*Tall one, there* he growled squeakily as the young one turned to nudge him back to safety.
The herd, when the young one echoed the calf's comment, swiftly joined them and watched as a dusky figure examined the area where the sphere had been buried.
Rhya Nui could sense the Kikanalo herd watching her curiously and turned to watch as the herd came down from their vantage point and approached cautiously.
*Who are you?* the chief rumbled as the herd stopped and let him move forward, though the calf managed to wriggle through the adults' legs for a better look, the dusky spirit smiled as the calf nudged the chiefs' leg.
*I'm Rhya Nui, Turaga Anuenue knows me* she explained as the herd gathered closer and the matriarch let the calf go and examine Rhya.
*Would you be able to help me move some of this rock?* the dusky Great Spirit asked, scratching behind the calf's ears as he nudged her gently.
*We'd be honoured to help, dusky one* the matriarch replied as the herd finished discussing what the tall one had asked.
Shifting out the way, the calf following her, the dusky spirit watched as the largest Kikanalo began pushing the biggest rocks out the way.
After several minutes the others moved in and began digging with their horns while the eldest female joined Rhya Nui and let her calf feed.
A clang suddenly echoed around the canyon as one of the Kikanalo hit the buried sphere and stepped back shaking its' head, dazed for a few moments before rejoining those now excavating around the sphere.
*Are you alright?* Rhya Nui asked the young Kikanalo as she came over when the chief growled softly, calling her to join them.
*Yes thank you, dusky one* she replied, moving to let Rhya Nui see into the hole, a fine layer of sand still covered the sphere and Rhya Nui jumped lightly down to brush it off.
*How will you get it out?* the chief rumbled curiously, then the herd stepped back surprised as a glow formed around the sphere, lifting it out the hole and gently resting it nearby.
*You are more than you appear* he added, lowering his head in respect as the Toa like being climbed out the hole and sat on the edge.
Mata Nui's sister smiled and stood up, *Thank you for helping, it would have been dull working alone* she replied, gently brushing traces of soil from the chief's nose and horn.
The matriarch snorted in amusement as the chief scuffed the ground in embarrassment, Rhya Nui hid a smile as he shook his head pretending the dusky spirit had tickled him and then turned to where the sphere rested.
The herd watched intrigued as the tall dusky spirit removed the lid and gently lifted out the sleeping matoran
*Oh she's pretty* the young one rumbled softly as Rhya Nui rested Rionna down before turning back to the sphere.
Replacing the lid, Rhya Nui glanced at the watching herd, *You'd better move back a distance* she warned, as her eyes began glowing.
The chief nodded and when the herd had moved away from where the dusky Great Spirit stood, they watched poised to move further if necessary.
Turning back to the sphere, the dusky Great Spirit's eyes turned incandescent as she concentrated on destroying the last of the spheres that had been made by the Dark Spirit.
The sphere began glowing as energy flowed from her hands, purifying the metal as it shrank and crumpled in on itself.
Eventually the incandescent light faded away and, as the herd watched, the dusky spirit lifted up the small ball of pure protodermis before putting it away.
*Are you alright, dusky one?* a gentle rumble came from the young Kikanalo as she moved to stand beside Rhya Nui, the spirit glanced at the Kikanalo who watched her anxiously.
*Thank you young one. I will be* she replied, rubbing the Kikanalo's nose before moving to where the yellow/pale green matoran lay, one of the others now shading her from the suns heat.
Rhya Nui then knelt beside Rionna and lightly passed a glowing hand over Rionna's mask, *We need to take her somewhere to sleep the healing draught away* she said after a few minutes while gently picking Rionna up.
*We'll be going past Keetongu's cavern and would be honoured to take you there* the matriarch growled softly while her calf sniffed curiously at the sleeping matoran
*Thank you, that is most kind* Rhya Nui smiled then she joined in the laughter as the calf began racing around excitedly growling about going to see his friends.
