Something has been bothering me about "The Storms of Poko Kohara" for some time. I ignored it during the beta, and didn't give it much though as I was blazing through it once the game released due to over exposure, but replaying now I see a fairly glaring plothole.
When nearing the end of the quest we learn that the Storms are caused by Anaharu, who after loosing (and dying?) doing the Trial of the Waves corrupted the adra pillar via which he was to travel to In-Between. The condensation of essence created unnatural storm around the island and Anaharu hoped that this will keep foreign powers away from Tikiwara.
However, the rest of the narrative doesn't seem to align the death of Anaharu with the apperance of storms. We knew that the Trial of the Waves happened sometime during the visit of Valian explorers - Vektor mentions seeing Anaharu and Tikiwara chief leaving the village late at night and only chief returning. At the same time, the chief doesn't speak of storms as it is a new phenomenon - mentions they never sail near Poko Kohara for a reason etc. This journal also fits:
Storms should begin during the Valian visit or even after they have left. I would expect something more alligned with: Valians went there are unleashed something unnatural.
