Recent reports from villages and settlements in close proximity to the Glothyris Sea lake state that villagers have gone missing, with witnesses claiming that a giant monster walks out of the lake, grabs the person closest to the water, and drags them back down.
Local police dismiss such gossip and are taking necessary precautions to prevent more kidnappings
*QUEST POINT*
The obstruction is from the local authority probably blocking entry to certain areas (caves, roads, etc.) because people get kidnapped every night.
The main character may take it upon himself to phase out the kidnapper by his own hand, instead of standing idly by watching innocents go missing.
*insert quest to kill Glothyris Giant*
Routes are opened up as an effect of clearing out the threat
