Your icelings begin to expand your caverns at E3 and F3 as well as D5 and D6.
Nothing of note has been found in the new cavern tunnels, except for a small opening in the ceiling of D5. Sunlight reaching into your cavern. This has some advantages as well as disadvantages.
If you manage to build a stairway upways, or get a fine climber, you can start to scout the aboveground area, but the same goes for the ones on the surface. As your tunnels now are connected with the overworld, you can be invaded as soon as a mortal up there finds out about it.
In the meantime you use your will to construct a summoning circle. With it you are able to summon more icelings at once, and higher class summonings are made possible, even though due to the primitive nature of your circle you cannot expect to summon archfiends. Maybe we should find out more about possible summonings.
