Star Wars The Old Republic: Ultimate War is a mod for Empire at War: Forces of Corruption. It features most of the Old Republic period in a massive compilation of conflicts.
The Derriphan is a ship that's pretty ambiguous and doesn't get much love. Personally, I love the Derriphan. All the Naga Sadow era ships have always had such a cool ancient look. I'm not sure about the role of the Derriphan yet, but it's definitely in the Jedi Civil War campaign and the Great Galactic War campaign.
love it!

I continually forget that Revan and Malak found the blueprints to these ships on Yavin IV, and had the Star Forge build them.
