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.
As the end of the Battle of Lumbridge came with Saradomin as the victor, constructs from the battle were left behind and buildings were in ruins. Players helped Foreman George and his team rebuild the town of Lumbridge; players gathered resources from camps left behind, and rubble from the back wall of Lumbridge Castle. These were used to rebuild the buildings devastated in the battle. Towards the completion of the buildings, a memorial fountain was built just outside Hank's shop, in recognition of all the efforts made to restore Lumbridge.
Angered by his loss in the Battle of Lumbridge, Zamorak sent a demon "San'tar Klaws" to kidnap Santa Claus and ruin Christmas. Players could gain 'naughty' or 'nice' points on Santa's list by partaking in numerous activities around the snow-covered crater. When 750 of either points were collected, San'tar Klaws would free Santa from his cage.
The former Saradomin camp subsided, and ruins from an old building underground were exposed. A battle ensued between gods Marimbo and Brassica Prime, based either side of the ruin, and Holstein, representative of the Godless, also arrived. Players could join any one of these three factions, and contribute by competing in the Cabbage Facepunch Bonanza minigame underground, involving monkeys and cabbages.
Players could take part in a choice of four different activities, including helping Santa Claus deliver presents to NPCs for festive paper to build a giant cracker, hunting tinsel snakes, helping take down a snowman boss called Snowverload, and going snowboarding. In addition to this, a number of bosses wore festive Santa hats.
During June 2015 the crater turned into a beach, organised by Battle of Lumbridge survivor Reyna. Before the party started, players needed to help her by bringing buckets of sand to the crater. The party itself features Distractions and Diversions portals, and activities (such as coconut shy, barbecuing, and sandcastle building), which grant experience. Clawdia also features as a boss that spawns every hour.
The crater and the ground dotted with green crystals are possibly a reference to the game Command & Conquer: Tiberian Sun, where an asteroid impacted on Earth creating a giant crater and spreading green plant-like crystal shards over the planet's surface.
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 since temporarily used during some events, and this "will certainly not be the end of it".
There is a single square located in the northeastern quadrant of the crater that causes the player to sink into the ground up to their knees. This is most likely a bug.
