I -was- gonna make this a silent page but. Since it's school, why not a history lesson?
If you're not familiar with the Tistow-verse map, you can find it here:

Jáhko's Tistow grandpa was one of the men who worked on the canal. He left Tistow specifically for the job and met Jáhko's grandmother during the building. This is another story I'd like to draw at some point, because young Ahku was very much against the works and did her best to sabotage them..
