The Felakgathar Contract was a deal between Danzar-Khâl and Surtur. In return for the gods and angels granting him residence in the realm of mortals, he would use his abilities and a small portion of minions to contain those he was once allied with or associated with in the Creation War. The areas that he helps ward and patrol are Felakgathar, Malurn, Azurâg, and parts of the prison continent Denerra.
Section 2, seal off Cruharr and do not re-open the area. Free the azer and let them go where they please.
Follow this contract to the letter, and I will call off the dogs. You can have your place among the mortals and even take some as worshipers if that suits you.
From Surtur's perspective, he had no choice but to accept this deal. He did not stand a chance against the mighty host that came to Svaer Hodgrolf. Even his old accomplice of the Creation War, Geb, was their aiding his former enemies. The deal was accepted not cause Surtur was backed into a corner, but because he could greatly benefit by staying in the realm of mortals and perhaps himself become one of these "gods". For Danzar-Khâl's part, he knew that Surtur benefited more by accepting the deal than fighting it out and being driven back to Chaos, killed, or entombed for eternity in some place like Denerra. The goal of Danzar-Khâl, and the others gods who conceived this deal can only be guessed, but it probably had something to do with having a former enemy on the inside of any future primordial machinations.
Theologians that have studied the Felakgathar Contract say that only Danzar-Khâl and Surtur signed the contract. Others gods and angels probably helped in creating and backing this contract, but because of Surtur's personality they wanted to make it seem like it was a deal between equals.
Habanin, once High Theologian of Thrakopolis, stated that the gods and angels gave up pursuit of Geb and Surtur because they were either too elusive or powerful. It is true that they were good at getting away, but this all changed when Geb was "convinced" to help Danzar-Khâl and his army strike a deal with Surtur at Svaer Hodgrolf. Some have theorized that Habanin's writing were biased at the time because of the near war state between Burterinii and Goth-Dyvermoir. By leaving out the fact of the Felakgathar Contract, Habanin hoped to not add fuel to the fire and be responsible for starting a full-blown war.
