The Treaty between Limsa and The Kobolds and how it was broken

[Nialle]

Limsa Lominsa needs mineral resources for their rebuilding effort, and so they broke their treaty with the Kobolds and started mining in Kobold territory (since all underground is supposed to be Kobold land according to their treaty). Then when Kobolds fought back, Limsa Lominsa started killing them.

So the Kobolds summoned Titan.

Basically Limsa Lominsa are the bad guys in this situation. They see Titan as a threat and Kobolds as a nuisance and seem to not really care to solve the situation in any way other than with violence, because their only option besides killing Kobolds is to stop mining for the resources they need, and they don't want to do that. They made a treaty that they only respected for as long as they didn't need to take stuff from the Kobold lands -- the minute it became in their self-interest to ignore it they went and broke their word.

It seems to me that most of the reasons why the beast tribes are mad enough to summon their Primals in the first place are because we 'civilized races' keep treating them badly. The Ixal are simply vicious territorial jerks, but I'm not too sure as to why the Amal'jaa are mad; though it's not like Ul'dahns are known for not being greedy so maybe it's another conflict over land rights.

The Ascians basically just give them the knowledge and tools to strike back, since otherwise the beast tribes can't match the military power of the city-states to stand up for themselves.
