Rituals

Rituals are a game mechanic in the Eye of the Vortex campaign, introduced in Total War: Warhammer II. Rituals involve a set of objectives that a faction must follow to win the campaign.
Some playable factions have other objectives instead, and ignore the rituals/vortex. For instance all Tomb Kings and Vampire Counts factions. See Eye of the Vortex#Playable factions for more information.
==How they work==
In the campaign, each of the 4 main races (divided into playable factions) has a set of rituals they can perform to influence the Great Vortex. High Elves' rituals use blue magic trails; Dark Elves' rituals use purple trails; Skaven rituals' magic use green trails; and Lizardmen rituals' magic use orange trails. The Vortex Victory is one method of winning the campaign.
Rituals progress in a linear fashion, one after the other. During a ritual, three of your settlements funnel magic across the map to the Great Vortex. A successful attack on any of these settlements will cause the ritual to fail if the settlement is not retaken before it ends. Rituals take up to 10-20 turns to finish, so the settlements must be protected from Warriors of Chaos, Unknown Skaven Clan, and Norscan Tribes factions who will spawn nearby, and from enemy faction armies.
Each completed ritual will cause an animated cutscene to play, and provide some story mission/content. 
Diplomatic relations will permanently be increased between the ritual faction and the other factions of their race, while it will permanently be decreased between all factions of the rival races. After completing the fourth ritual, the ritual faction will be locked into war with their rival ritual factions. Diplomacy will no longer be available between these factions.
Eventually, players will have to complete The Final Battle. The first faction to complete their final ritual must defend The Vortex from the rival factions.
==Ritual currency==
Each ritual has an increasing cost of ritual currency, and has different effects. Ritual currency is generated through settlements, treasure hunts and other dilemmas, winning battles and also through ritual resource sites. The ritual currency is different for each race:
* Skaven - Warpstone
* Lizardmen - Ancient Plaques
* Dark Elves - Scrolls of Hekarti
* High Elves - Way-fragments
==Interventions==
Intervention armies can be summoned while another faction is in the middle of performing a ritual. These armies are AI controlled and generally attack the enemy settlements involved in their ritual. Interventions come in 3 levels, which cost different amounts. If you were not already at war with the targeted faction, the game will ask if you want to declare war when summoning an intervention army.
