re: true or false?

Quick question! I’m having trouble differentiating between what is fanfic and what is canon for Critical Role campaign 2 (to be fair, the fanfic was amazing).Did Caleb write Molly a letter explaining, “You are Mollymauk Tealeaf, part of the Mighty Nein. If you need help, head to Zadash,”? Or something to that effect?If someone could help with a link I’d greatly appreciate it, thank you!

I like how Liam said he was leaving a letter, “Telling him to find us through the Gentleman.” But not saying he wrote his name or anything else, just that.

Then he tucked it in the lapel of his clothes. No mention of Zadash, no mention of safe places to go or stay, zero mention of the Mighty Nein at all; all he said was the quote above.
