As of the events of Forsaken, the House of Judgment has been somewhat rebuilt by Variks using various Fallen prisoners who he has released from the Prison of Elders. Their current goal is to reunite all remaining Houses and factions within the Fallen, and return to the traditional ways of the Eliksni, before the Whirlwind.
House of Judgment reputation is increased by completing Prison of Elders activities. Each completed round of the Arena gives reputation. The level 32, 34, and 35 challenges award 200, 300, and 500 reputation respectively, upon conclusion of the final round, along with the individual round gains.
