Total War: Warhammer II, Can every faction win the vortex race?

Solution 1:

As it turns out only the major factions (The player) and the remaining 3 others main ones can work towards claiming victory using the vortex.

This means situation

Player is High Elves,

• Mazdamundi for lizardman
• Malekith for dark elves
• Queek for Skaven

In Case One of the 4 Major factions gets confederated this faction will then takeover the race for the vortex. Here are the scenario's:

• Order of Loremasters confederates Lothren
• Naggarond gets confederated by the Cult of Pleasure
• Hexoatl gets confederated by Last Defenders
• Clan Mors get confederated by Clan Pestillence
