Chapter 1 - Unwelcome visitor

This is the Part 2 of The Iudex's Day Off! If you have yet to read that, please do so first before starting this one!
This takes place after the end of Fontaine's archon quest. Be mindful of spoilers!

"Who is here to see me?"
"The dendro archon, Monsieur." Sedene repeated.
"The dendro archon?"
"Yes, apparently she brings urgent news."
Just what kind of news would be so urgent that it would warrant an archon leaving their nation?
