Lumbridge Crater

The Lumbridge crater is the site of the Battle of Lumbridge, where Zamorak returned to Gielinor and clashed with Saradomin over the power of the Guthix contained in the cave system that lies below Lumbridge and Lumbridge Swamp.

Creation
A few days before Zamorak's arrival, a portal appeared in the woods between Lumbridge and Draynor Village, just south of an abandoned, 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 that 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.

Battle of Lumbridge
Saradomin and Zamorak stand at opposite ends of the crater, still battling with divine magic. Their followers have set up camp around their feet, and are encouraging adventurers to join their cause, to fight in the Battle of Lumbridge.

The power underneath the crater has been released, and can be collected, in the form of divine tears, by those faithful to either of the gods, using the Mining, Woodcutting and Fishing skills. Adventurers may also strike at the warriors of the opposing god, who drop tears, pieces of sacred metal and parts of divine weapons to make weapon overrides.

Wisps
The first colony of wisps, residual life energy created by the remnants of Guthix's power, are found here in the crater. They release the divine energy needed for the Divination skill.
