This week Julius and I explore a RPG about exploring a giant castle.  Giant doesn't do this castle justice though.  This is a world inside a castle so immense there are seas in it.  The castle is filled with room so large there are cities and villages in them.  You will wander around exploring and fighting Rooks, massive creatures made of stonework.  When you defeat one, you can gain powerful magic stones, Rookstones.

Colostole is a solo RPG by Nich Angell.
