A good ending to the day. 

It is.

Brigid will watch again over the night, and in the morning when Ling is ready, they can set out.

They'll push hard the first leg, try to make good time while they're relatively unchallenged. 

Seems like they're still out in front of the pursuit, for now. Still, they should cut further south than they would otherwise, to skirt around where Ling met Brigid. That'll be where the search starts.

A sensible plan. (She of course wants to know more about how their enemy will be searching.)

Possibly more val'kyr, depending how likely the Lich King thinks Ling subverting others is. Gargoyles, flying animated stone monsters for aerial coverage otherwise. Frost wyrms are being kept in reserve and they're passing through territory that living dragons frequent reasonably often so probably no frost wyrms. Zombies to scour the ground.

What are dragons? 

So glad she asked! Dragons are large scaly reptiloids, four legs, two wings, a tail, horns, great big teeth, about the size of a house, very powerful in both the magical and mundane spheres. A fine draconic specimen has just appeared behind Ling and Brigid, and would like them to land now, please. (The dragon has dark scales flecked with silvery shine, like the nighttime sky, and wings whose membranes trail off into gossamer ethereality at the edges.)

That is not a type of dragon Brigid has heard about before. She would rather not fight it.

She may land.

The dragon lands behind them, something complicatedly magical happens, and a human woman with hair the same color as the dragon's scales including the shards of starlight embedded within bounces over. "Hi there!"

"Hello."

"Who do I have the honor of speaking to?"

"You can call me Zera. As for who I am... In a certain sense, I'm responsible for your presence here. Or at least, I'm the one who permitted it to continue."

"That implies much power."

"You're right, it does. But I am a dragon, after all."

She inclines her head a little. "Why did you permit my presence?"

"Because I prefer stories with happy endings."

"...I'm glad that I landed when I did. It would have been - a sorrow for the world, if my companion had fallen."

"That I take no credit for. I'm here now because otherwise in" she looks up at the sky briefly "thirty-eight minutes twenty-two seconds my younger self would have intercepted your flight path and ended this little diversion from the main timeline."

" - Your younger self???"

"Back when I was small and blonde and still believed that there was such a thing as a true timeline to be protected."

"You have the ability to move through time?"

"So do you, you're doing it right now." She laughs. "Why don't we get a bit more comfortable, it'd be better for you to wait before continuing on."

...Sure, why not.
