would Angels fight Lizard men i meen they are both children of the old ones?
is there a blessed spawning of Seraphaal? do angels speek Lizzie?

i thought about this because all warhammer armys must fight each other (you can have misunderstandings, rebellions but with Lizzies vs Angels i just dont see it, i can under stand a acidental clash or something like that but with anything other than vengeances on one side and at lest a skink preist to act as a channeling point for a slaan the fighting would break up as soon as they realised what is what (you can't have night fights every battle folks) :(

well the empire and bretonnia are technically allies i think, but they can fight, and brets have good relationships with the dwarves...they can all still fight each other

As a lizzie player, here are a few suggestions.

Why no spawning of Serphaal? Serphaal never guarded the spawning pools, so the lizzie's don't get his spawning.

Lizards speak their own language, not the language of the gods.
Only the slann still speak the language of the gods, so I gues only the slann can really understand the angels if they speak in their own language.

The reason for fighting the angels just like any other, they didn't help the lizzies, so they too are intruders if they enter the lizardmen jungles.

Well i think this is one where we have to just be logical.

Serraphal did not have spawning pools because he was to busy fighting daemons, and he only turned up just as the warp gates burst open.

Officialy Angels and Lizzies should have some sort of "The enemy of my enemy" pact, however if angels are going through a forest looking for what they belive a daemonic monument while burning down the jungle around them then the Lizzies are going to attack, and if the lizzies come to close to Nirvvana the angels want em dead.

We cant stop two armies fighting each other, its just one of those things i suppose....
