Radian could help her with the
Whispers of the Mountains plot.
It'd be nice for him to stretch his legs a bit and help someone out, he doesn't like to see people unhappy. He just wants life to be good for people. He's usually very laid back about a lot of things and because he can't fly he can definitely keep up with her.
His mother taught him the best way to climb moutons and to use his hooves to his own advantage in those situations. :3
It'd probably be a meet and greet / whispers of the mountains cross, since they've never met before.
Side Note:Nemesis could always save her from the swamps, and see that she's okay (because he's big, tall and strong) but he probably wouldn't stay around too long incase he creeps her out a bit.
