"Who told you that?" He asks sharply. "None of my knights should have shared that with an outsider."

"It could have been plucked from their minds with a Detect Thoughts,"  Sir Isteval says. "No magic I've ever heard of can send someone back in time."

Like most people in Faerûn, he is ignorant of all the methods to do so which do exist.

"Yeah, going back in time is a good literary device, not something that happens in the real world. And yet... these memories come from... somewhere. And the most important of them is probably how it showed my death. After a week of flying east we got attacked by a red dragon. It didn't have magic, so it mustn't have been too old, but it still sliced through our flyers, so maybe it didn't need to use any?"

"I died trying to bring it down - I had underestimated how much fire a red dragon can breathe, I am resistant but it wasn't enough, and then it grabbed me and... well. Squishy mage, grabby dragon, the ending is overdetermined. Would have still been worth it if it allowed the others to bring it down or at least escape."

"How big was it? Horse-size, or bigger?"

Sir Isteval gives Thurl a questioning look.

"The Cult of the Dragon has made a lot of enemies. We don't need to know which one gave you those memories to guess they're enemies of our enemy. Being particularly vigilant on a specific day shouldn't be a set-up for a trap. Can you remember the details of where and when the dragon struck? Any landmarks? Or are we going to have to bring you along to jog your memory."

Reed takes a couple steps back.

"I'd say about this size" he points at the distance between him and Thurl "from snout to the base of the tail."

"I'm happy to come along, but the issue is that it was a really foggy day, the only landmarks were some mountain peaks in the distance... oh, that night we had slept in an abandoned old amphitheatre? Lots of red stone."

"An amphitheater? Sounds ancient Netherese, or Anaurian. Red stone would place it in those iron-rich parts of the Serpent Hills. The dragon... Landillew, perhaps? She has been known to target armed bands of adventurers, and to strike from the air rather than wait for them to come to her lair."

"Yes, you'd better come along. We'll get everything you can recall and drill on counter-dragon tactics on the wing. Heavy crossbows as standard equipment for all over lances and swords, and a more dispersed formation once we're in the region."

"You know the passphrase for the camp already, we'd have a heard time keeping you out," he adds gruffly.

"Meet you at the camp then!"

He'll go bother Delfen for Mirror Image. Or maaaybe Resist Energy. Yeah, Resist Energy sounds like a better plan considering... everything.

"Darkness and air."

"It's 'Air and Darkness', but go on through."
