The rift Fihrgrell Drain was created in the Demon Spawn War by engineers serving under the Covenant general Abbathor. Detonating a null mine, they tore a hole in the Web of Magic, creating a rift between Bal-Kriav's Ratanur Trap and the Abyssal world Kurun'Ush. This risky operation, one bound to attract weave spiders, was done to counter the effects of the Moredhel-Fihrgrell Rift. When it opened, it sucked the seawater coming out of the Moredhel-Fihrgrell Rift, sending it back to whence it came.
On 9 Bloom 254 GE the Fihrgrell Drain was sealed by weave spiders.
