Ultratech

Ultratech is a class of items one level above Spacer technology, and may be more or less equivalent to Archotech technology. Some ultratech items can only be obtained through Ancient Dangers or Quests, while others can be researched.

Origin
Since ultratech items do not come from Glitterworlds, many theories are plausible. The plasma weapons are effective at fighting insectoids, so a long-forgotten civilization could have developed the technology before being wiped out, thus leaving these items behind for others to scavenge.
