Albegad is an important Deltan colony world, designed to closely mimic Delta.

Deltan planetary engineers used orbital bombardment and tractor beams to redirect icy-asteroids to terraform the planet as well as reshape the tectonic plates. Later Federation ecological preservation policies would forbid this, though it is a historically significant example of procedure before these rules were enacted. It is considered a "virtual duplicate" of Delta. (TOS video game: Starfleet Academy: Strategic Command)
