Did you mean "clearing" as a different path or somethings like not a main quest?? if you understand what i'm sayin.My current focus quest is about the "Giant Plant", because i want to get in the villages (spoiler alert).
Its like an extension of the Cassie quest after the don quest, just get to the desert city and explore it thoroughly. You'll see what I mean.
Im not sure what classifies as a "main" quest since the quest system is still vague and it varies on the players interests but the desert quest is a part of the logbook so...
