Consider it like this:
Parties 1 and 2 are banking on a 'noble, back-to-the-land, magical heritage, the best blend of magic and high technology' vibe. They want people who look for strength and power to see them as strong and proud and powerful; they want people who look for granola and rainbows and unicorns to see them as eating granola, generating rainbows, and petting unicorns.
Party 3 is banking on a reputation of literally cut-throat tactics in business and politics, rips everyone off, sells drugs to kids in the playground, captures the opposition and chops their heart out of their chests and televises this on their high holy days, and has the attitude of 'you don't like it, you can kiss my ass - kiss my ass, baby. Kiss it. Pucker up.'
So what do you think?
Add into the equation the behind-the-scenes facts that Parties 1 and 2 are established by Immortal Elves, and Party 3 is most likely at the very least playing host to something so horrible, ancient, and literally Corrupted they would all for once band together to rain mystic nuclear fire, real nuclear fire, and every Thor shot they could beg, borrow, bribe, or steal down upon it and damn the consequences if they could manage to get accurate targeting.
