The Viper's Den is an area created to support the Ghost of Iki mission on Iki. This area is a secret port where smugglers live and move packages on and off the island. At the time of the story, the area has been cut off from Tsushima, but later becomes available for travel. The player is given choice throughout the mission, and has the option of fighting the Viper in an optional Duel.
I was responsible for supporting the Ghost of Iki mission as well as being responsible for the art of this area and its layout. I supported design, as well as setting the stage for the optional duel.
