A summoned Evil Lord Wrath created by Demiurge participated in the invasion of the Roble Holy Kingdom at Kalinsha. He exchanged places with his superior, Demiurge after the Paladin Order had seemingly blasted him in a ruined house. Taking on the guise of Jaldabaoth's true demonic form, Wrath displayed that he was immune to their pitiful attacks and to further demoralize them used Queen Calca as a bludgeon.
Later on, news of Jaldabaoth's new transformation was brought to Blue Roses by the Holy Kingdom's delegation. Jaldabaoth's appearance confused the adventurers as they could not determine why the demon chose not to reveal his true form at Re-Estize while fighting Momon of Darkness.
The Evil Lords' level were estimated to be around 80 and are capable of calling forth an army of demons. However, it comes with a recharge period in doing so once a single day.
Of all the special abilities that Evil Lords possessed, the most dangerous one was the ability to summon another Evil Lord which was lower level than themselves. However, summoned monsters could not in turn summon more monsters. Therefore, the Evil Lord of Wrath that Demiurge had summoned could not summon another Evil Lord.
If there was an Evil Lord that had been created or made, then it should be able to summon additional creatures in their rank to fight alongside the summoner.
- The Evil Lords are all named after the Seven Deadly Sins.
