In the Demon Spawn War (89 GE - 269 GE), Tharum was the southern arm of the Inghild mountains. The demon lord Ogtha controlled the south, and the Covenant the highlands north of the Viiz Bo river. In the southern mountains were based the armies of Ogtha, guarding an inter-system rift linking their Abyssal home world to the battlefields of Bal-Kriav. Ushered through the rift, demons thirsting for plunder and bloodshed, were given the basics, armed, then rushed to the front.
It took two centuries of trying, hundreds of our best agents killed or worse. Our saboteurs got past Ogtha's deep defenses, over walls, and past towers, bypassing the trenches of the dead, and past forests of evil predatory creatures and demon patrols. On a one-way mission, they reached a pond that smelled of death. They probably looked about and saw the help throwing hooks into a pond of brackish water. They were pulling the drowned out, or snagging those swimming up from below. In the deeps of this pond was the rift to Ogtha's home world Kelresson. Based on the plan they entered the waters invisible, then swam down to the rift's opening where they set-off a null mine.
I know whoever reads this may question my allegiance, but if it were not for Rilthang's assets, these noble sacrifices would have been in vain.

The explosion from the null mine caused another rift to temporarily open next to the existing one. This counter rift merged with the demon rift, causing the land to buckle, split, and then float upwards for hundreds of feet, pushed apart by a wave of entropic energy. Once this wave dissipated, the broken landscape fell to earth killing demons in the tens of thousands. The rift was closed, and the landscape a smashed rugged landscape of broken rock, great boulder fields and deep crevasses, the remnants of mountains reduced to rubble.
Late in the Horgon Era, Tharum became the home of stone giants in the hundreds. Refugees of the Gadstill Dynasty (275 HE - 1533 HE), they founded the settlement of Saer'kal along Tharum's western ramparts. Today, some of the best stone masons and engineers come out of Tharum and the shops of Saer'kal.
