Halls of Power is a series of Episodes focused on characters from both New Genesis and Apokolips.
League Halls is released in a Free Update prior to Halls of Power and includes Leaderboards. The first Halls of Power episode includes attacks on League Halls and Apokolips content.
- Halls of Power Part I
- Halls of Power Part II
- The rest of the story line is not released in a "Halls of Power" episode, but as one of two unrelated instances within small episodes:
- The Will of Darkseid (part of Episode 23)
- Darkseid's War Factory (part of Episode 24)
The Halls of Power story line's connection to the Source in a sense makes it a prelude to the whole Source saga in DC Universe Online that ultimately cumulated in Dark Knights (Episode).
