According to the DeLambert they're a very peacful trading race. They claim to be from Gas Giants and trade on the "Primitive" SST. Primarily they trade several glyphs at a time for 15-20 Essentia. Some Trade Ministry deals have gone to a 93.4 Essentia deal for several glyphs. The Del have also been buying small trades off of the SST.

Not much is known about them but some players have sent ships to them. Most Notabaly is a player attempt of 480 Sweepers and 20 Scanner force sent against they're home planet. All of them were totally knocked out. 

A colony seems to have the following buildings

• *40 Spaceports

• Propulsion Lab
• Pilot Training Facility
• Spy Buildings
• Crashed Ship Site
• Interdimensional Rift

*Note the exact number of spaceports does vary from one colony to another likely based on the size of the GG.  One recently viewed colony had 60 spaceports.
