School of Growth

 is a building of the SUN.

Background
It costs 7000 Resources to build. Any unit with Builder skill level one can make a School of Growth, provided a House of Justice, Lookout Tower, and Garden already exist. Within, you can train a Farmer to become a Defender, or a Farmer with potential to become a Cavalier. Training an Engineer yields a Ranger, an Engineer with potential yields a Druid. A School of Growth is required in order to acquire a Sanctuary House. Upgrading this building provides a Corral.
