A few weeks before Zamorak's arrival, a portal appeared in the woods between Lumbridge and Draynor Village, just south of an abandoned and derelict house. Various bystanders gathered to gawk at the portal as it grew in size.
When Zamorak stepped through the portal, he immediately noticed a glowing crack in the ground. From this crack radiated power, remnants of godly energy left by the death of Guthix. He started blasting the ground with magic, sending the civilians fleeing in terror and attracting the attention of Saradomin, who had returned to Gielinor earlier and in a more subtle fashion.
The two gods sent opposing beams of divine magical power at each other, which collided in mid-air. This occurred directly over a well of Guthix's power, the ground above which caved in as the gods battled over it. The energy involved in the contest soon overloaded and created a blastwave that tore up the ground, destroying trees, buildings and even the back wall of Lumbridge Castle.
Saradomin and Zamorak stood at opposite ends of the crater, continuously battling with divine magic. Their followers set up camp around their feet, and encouraged adventurers to join their cause, to fight in the Battle of Lumbridge.
The power underneath the crater was released, and could be collected in the form of divine tears by those faithful to either of the gods, using the Mining, Woodcutting and Fishing skills. Adventurers also could choose to strike at the warriors of the opposing god, who dropped tears, pieces of sacred metal and parts of divine weapons to make weapon overrides.
Even though the maelstrom stopped after the Battle of Lumbridge, the examine text still read "A vast maelstrom of energy", but was later changed to "An empty crater".
This was supposed to be the first, lowest level, divination location, but due to overlapping release dates (i.e. the Battle of Lumbridge was not yet over when the Divinationskill was released), the location got moved a little bit and was given its own little crater. Because there is little use for it, it was temporally used during the 2013 Christmas event, titled Up To Snow Good. As of now there is no use for it, but this "will certainly not be the end of it". Except for the Saradominist camp, which will serve as the location for the third World event between Brassica Prime and Marimbo.
