This planet blows.

Horizon is a human colony in the Terminus Systems where the Collectors struck and abducted most of the people there. Many of the Shepards on this wiki were there and tried to stop it.

Horizon is also a terrible place where friends and lovers can't seem to string coherent sentences together and have fights that lead to lots of sulking and drinking and oftentimes staring at a picture of the other person going over the stupidity that flowed from their lips a thousand times over.

I heard Horizon also has had a good Flip Cup team.

As a result of certain peculiar questions both received about Horizon, Bellara Shepard and Kaidan Alenko have determined never to go to Horizon. Whether they will be able to avoid doing so remains to be determined.
