interpretation of particle と followed by の


> 早｛はや｝くしないと、ヤツらとの最終｛さいしゅう｝聖戦｛せいせん｝の幕｛まく｝が切｛き｝って落｛お｝とされてしまうのだから……！

My doubt is specifically about the part ヤツらとの.

Several times I've come across the particle の being used right after another
particle, but I haven't had any luck finding material covering this case.

The most likely to be accurate answers I've been given is that the の particle
turns into a noun whatever comes before it - I'm familiar with that usage of の
- but with other particles just before の I have a hard time trying to make
sense of everything.




It is showing possession, as it usually does. Hopefully this can clear it up.

[code]

    ヤツらの最終聖戦 <- Their last holy war [with anyone]
    ヤツらとの最終聖戦 <- [Our/Someone's] last holy war with them 
    
[/code]

You will see the combination often.

[code]

    彼とのデート... A date with him
    敵との戦い ... A fight with the enemy
    
[/code]

I'm having a hard time finding any resources to explain it any further,
unfortunately. Hopefully that helped.
