No, her fear this day was unrelated.
Mother had summoned her, had made her an offer along their whispering link--a link which had, over cycles, grown and swollen like some living thing curling through her mind. A link that had pushed other thoughts gradually away. Ananke had begun with the mantis's gift a welcome distraction, a quiet reassurance when anxiety rose up. Reassurance had grown into advice, into direction; and that, in turn, into command. What had once been a murmur of promise had turned into purpose. And Ananke--grateful to have something other than fear in her heart--had embraced it, clung to it, subverted herself to it as if trying to cast aside her trembling self altogether.
Paws scuffled quietly across the powder, never sinking in, Ananke's light weight braced atop the crust. Here, at last, she stopped, for the depths of the tunnel before her were yawning with shadows. Behind her, the last of Ursa's "star"light gleamed; before her lay the unknown. It wasn't that darkness or tunnels scared her; on the contrary, they reassured her rabbit's mind. A burrow, a warren; that was safety; that was home. But she'd been invited to see Mother directly, now.
...Among other things.
Things that, while eager to accept, Ananke found that she rather feared.
Mother had promised her courage, power, strength. The chance to aid others, to help them grow and learn. To cast aside her fear altogether. And Ananke had never desired anything more in her short life than this; already she had decided to accept, no matter the cost.
She pushed into the tunnel, hopping warily at first, her senses hard at work to ensure she was alone. She reached out her magic, too, to call for herself a little light--the tunnels were far too large to navigate with whiskers alone, and she knew she had a long, long way to go.
The wisp that sparked up was cold fire, a lonely little blue-green light that looked far too small where it bobbed in the vast tunnel up ahead. Its light gleamed off the chipped ice walls, and Ananke blinked through the falling flakes of snow to stare forward.
Unsurprisingly, Ananke was afraid.
