Block, Frost, Prism, Teleport, Lightning and Generator are the six different crystals that you possess. You must use these crystals to protect your core!
With these crystals you can build the structure of your choice. But be careful you have got limited resources. You can transport energy from the core to the crystals and increase their power! Place generators under daylight rays and gain resources. Place your core to the most strategic place! You can create paths and control the orcs!
Everything is up to you! Determine your strategy!
