I suggest merging this article with "Trill (planet)", as there seems to be universal agreement (although never stated in canon) that Trill, the Trill Homeworld and Trillius Prime are all the same planet. – The preceding unsigned comment was added by188.8.131.52 (talk).
If it was not mentioned in canon, then we don't mention it. We already mention that the Star Trek Star Charts make that connection. 31dot (talk) 20:13, October 3, 2013 (UTC)
