Jungle Skirmish

The Jungle Skirmish (also known as the Gravesend Event) was a battle that took place between Finnick and roughly a dozen members of Guildereim's society. It began as the group formed a search party at the Golden Tether to investigate odd occurances in the jungle, and located Finnick pouring concentrated Necora into the ground; this would later open the Tether up for larger infection outbreaks and make the island vulnerable to exterior attackers.

The battle ended with Trygve's abduction. Finnick left behind several clues as to his next whereabouts, but they were later revealed to be traps as part of his plan to reclaim the Black Tomes. Finnick brainwashed Trygve into later ruining Guildereim's reputation and stealing the Black Tomes; when Trygve, Jacob Cross and Florian later followed up on the 'clues' left behind by Finnick, the latter took the books back.
