Need help with quests, dialogues, scripting

[Lame Stallion]

Hey there! I need scripting help for my project. I'm creating a campaign with which I've already started the script, and I will be busy with some additions to it, level design, gameplay and soundtrack. Need someone to help me with quests, characters and dialogues. I've already created about 5 characters, so I need more dialogues for them, and any subsequent contributions are appreciated. I will tell you the script, story, and the background for the world (the campaign is set in my universe) and characters.
P.S. The picture is hinting at the protagonist.
