<Snipped quote by Hael>
Watch what's going on and decide the sea is better for them. Mark land on all their maps with 'Here Be Monsters' and leave it at that.
Mer 1: "These ocean are awful! Daily we are hunted by Terrorfish, Devourers, Stormhunters, and we never know when Kraken's going to smite someone! We have to take turns begging him for mercy on a regular basis."
Mer 2: "You know what? I think you've got a point. Let us venture up the rivers to the land, and see if a better life waits there."
*the Mer travel up the rivers. They see Zerabil stabbing Cimex, the Battle Brothers being eaten by dragons, everything's on fire, there are plant people walking around and aiding in the aforementioned Cimex-stabbing, the Garakai are slaughtering all non-corrupted people, and some
invincible nutcase is shouting about "Mighty" something.*
Mer 1: ....
Mer 2: ....
Mer 2: "...So, do you want to beg Kraken for mercy this time, or shall I?"
