Kai stopped not far into Leo.
There were a few reasons for that. First, after the dimness of the tunnel, it was bright: the light sparkled off the waves, filling the air with its glow, and she had to stop to let her sight adjust. Second, it was grand: she felt she had to give her first glimpse of its enormous expanse a good few moments to sink in, as if the cave itself deserved respect. Third, however, was that she was here with the Prince of Void, and as its Knight of Flowers, it was her duty to ensure that the area was safe.
At least, that's what she'd decided; and Veil hadn't really seemed to disagree with her, at least not in any way that she'd been able to ascertain. They had met in Pisces, and in their first stumbling, clumsy and hesitantly friendly encounter, had come to a few conclusions. So far as they could tell, they both existed (probably); The-Veil-The-Veil-The-Void was a Prince (maybe); and Kai was therefore its Knight (somehow). Finally, and perhaps the farthest leap of logic: as Prince and Knight, they were destined, or perhaps obligated, to go on an Adventure.
And that had brought them here.
Perhaps belatedly, she concentrated on the plants: the grass, the trees. Her magic was still primarily untested in its strength (she'd lived most of her life wandering aimlessly around Eridanus), but it seemed wise to try and use it now--to get some idea of just how safe Leo might be. She'd never before, after all, seen any place with an ocean, or at least a great bay; she'd never seen the towering sea stacks and smoldering volcano, or anything remotely like it.
A moment's focus and her senses were whisked away, carried off among the plants of Leo: she could better sense the sea breeze, the brush of warmth from the volcano's tunnel, the presence of Lessers in the forests and beneath the waters. When her mind came back, she reeled for a moment, then turned to blink owlish eyes at Veil.
