Alright, cool! Nice JP. Long, but it was good!
I'll try and have the post up before I go to sleep, if not, then tomorrow morning.
::EDIT::
Okay, so a really long post, sorry about that. Things may get confusing, so allow me to clear some things up:
1) Avant's dad was originally a member of The Shadow (aka the resistance group growing in Twinleaf). He was kicked out and refused to stop his meddling, which concluded in him getting a visit from them personally.
2) It is night/evening time, if it wasn't clear. It's dark out, although not complete darkness like if it was midnight or anything. Also, the giant flying figure at the end is actually a Pokémon: Salamence. You can try to battle it if you want, but you won't win. It's mainly there for tension and stuff, and destroying/burning down buidlings and nearby forests and whatnot. Also, the Salamence is owned by The Bronze Soldiers. The Shadow grunts/members have Houndours as their Pokémon.
3) The Bronze Soldiers and The Shadow members are mainly going to be fighting within amongst themselves, so unless your character somehow gets accidentally mixed up in the fray, they may or may not be attacked (this is up to you). The Bronze Soldiers won't hesitate to attack if they suspect you of being affiliated with The Shadow (given the circumstances, it seems like an appropriate action), and some may try to burst in through your doors, or even the Salamence may be used. The Shadow on the other hand, won't attack unless you get in their way. Although some may try to persuade you to join, many of them will leave you be. Both soldiers use swords/bows/spears, etc.
4) It said in the sign-up you need a weapon, but this is not all mandatory, as you do have Pokémon. But in case you still want your weapon, try to find it somehow during this part.
5) Also, no killing. Don't kill Pokémon, and don't go around slicing people's heads. That doesn't seem so difficult, does it? If your character doesn't want to fight, that's fine too. The main purpose of this part is to reach the outskirts of town. If your characters want to run into each other and team up a bit that's fine too, so long as you make it to the outskirts.
6) And lastly, the purpose of the raid is not to kill people, but rather weed out possible Shadow members. By doing this raid, they are essentially going to strip The Shadow of their birthplace and hopefully eradicate the group.
