Campaign Notes
Nale met the party for the first name in Bavland after the party left the Envisagers hideout. He charged the party to take down the Envisagers and make sure that the organization was destroyed. During their conversation at the Bavalnd Glyphpool, Nucko tried to steal a button of Nale’s jacket. He failed, and Ravan had to roll a nat 20 to save Nucko and convince Nale to give Nucko a button from his jacket.
After the party (and by party I mean Kael), had their adventure with the Envisagers in Kharbranth, Nale showed up at the Glyphpool, paid Nucko his button, then immediately tried to kill the party. He argued that the each member of the party bonding a spren made them dangerous and at risk to bring back Odium.
After he summoned his shardblade, Leif made a dozen duplicates of himself and told Nale that he would make an enemy of him if he killed the party. Faced with an impossible choice, Nale turned and left the Glyph Pool.
