Inside the tomb where the two Demon lords were unsealing their brother, the Lord of Corruption was desecrating the heroes' statues. Looking for a way to stop them from awakening.
The Demon Lord of Affliction was busily opening the seal. With him on the task of unsealing his brother, he was able to do it faster. Even without the help of his followers, he was fast enough. He was able to reach halfway on unsealing his brother. Non-other than the Lord of Chaos. Pulsating red was transpiring currently as the seal was weakening. Making them get closer to their goal.
The Demon Lord of Corruption used the blood of the guards they have killed. Bathing the heroes' statues with their blood while chanting in their language. Soon after, they felt that entities were fast approaching their location.
"Brother, we have company," Said the Demon Lord of Corruption.
"Yeah, I know," He said to his brother.
