Some theories on "Earth" type planets would lead you to believe that the vast majority of such planets would be entirely covered by water and that one with some land above water a rarity. The idea that Pisces was a water covered planet would fit well with me.
It is very conceiveable that a trinary system could have many planets with the potential for life and that radiation from non-primary suns on each planet would be a non-issue. If our own Jupiter was a bit bigger we might have one bright sun and one slight sun whose light varied depending on where our orbits were around the sun relative to each other at any given time.
In such a system you could see three separate solar systems revolving around a common center of gravity. After billions of years of interaction we would have stable planetary systems revolving around each of the three stars. If we had three Sol type systems revolving around such a center maybe we could have an Earth in each and a Terra formed Mars and Venus in each as well as "worlds" that were moons of the various planets. To get twelve worlds maybe all they really have around each sun is an Earth (World 1), Luna (World 2), terra formed Mars (World 3), and a colony on a Jovian Moon (World 4) times 3 stars = 12 colonies.
