An avian species evolved on a densely forested planet. The Quelif possess impeccable physical senses and are capable of translating the body language, speech, and pheromones of alien species incredibly well. They utilize this natural talent to open fair and honest negotiations with other races to ultimately allow for the establishment of trading colonies on their worlds. Trading colonies are the only form of stationary population centers outside of the Quelif homeworld. They cost less to maintain, cannot build ships or defenses, grant the Quelif homeworld a percentage of the planet's total FISD, and can construct additional buildings to improve the planet further. Their trading fleets network their colonies, sharing a small percentage of each world's FISD to the other planets. When constructing fleets outside of their homeworld they rely on specialized construction ships to manufacture them.
