The BUILD DEN Order
Phase: Development Phase

To build a Den the BUILD DEN order is used. In an empty hex it takes 50 or more Grey lizards two consecutive undisturbed turns.
Instead of building a completely new den, 50 or more Grey Lizards can convert a Ruin into a Den in a single turn. Dens may not be built in Swamp, Peak, Volcano, Cursed, Water or Whirlpool hexes.

Example:-

Build Raft <HEX>

*where HEX is the code for the location where the den will be BUILT.
