The Second God Wars

Cause
In the fifth age, year 169 (current year), there has been a major conflict between a group of Saradominists and Zarosians over the control of the Daemonheim dungeons and chaotic weapons. It began as an expedition to find gravite and chaotic ore by several Saradominists, but then they noticed that Zarosians had occupied the dungeons, which were once in Saradomin's control. A fight broke out near the surface between a group of ten led by Lord Zilyana and hundreds of minions of Zaros, including battle mages, warriors, rangers, brutes (large henchmen), and even some trained creatures that aren't of this world. After Zilyana called for reinforcements, his forces advanced and strucked the sixth floor by dawn of the next day.

Saradominist Alliance
Although it has not yet been confirmed, Armadyl's representatives have spoken of joining Saradomin under the winged god's behalf. Also, despite Guthix's philosophies of peace, several dwarves and gnomes claim to have formed a militia that will target the army of Zaros.
 * Saradomin Alliance (confirmed sides) - Asgarnian military, Mistalin military, Camelot military, Fremmennik military, Dwarvern and gnome militia, and the Tirannwn military (possibly others)

Zarosian Alliance
Zaros seems to have the strongest side, since all of their allies have made a bold confirmation. Zamorak and Zaros made a strong diplomatic decision to reunite. Bandos also chose the Zarosian side since his alliance with Saradomin is quite weak.
 * Zarosian Alliance - Troll Country, The Bandosian Empire (all goblins, ogres, orks, etc.), The Black Knights, Khazard's Army, The Mahjarrat, The Meiyerditch army, and Ardougne is suspected to secretly be providing Zaros with weapons.
