I can break it down pretty easily.

 "When a gate was slammed down, he was formed from the persecution and ridicule placed on a being in another reality." 
This refers to us denying any form of involvement with his roleplay.

"His sole purpose, by any means, is just to force them to realize the gate, open it, and cause a war between this reality and the other side."
This clearly means that the character's purpose is to open up a link between our roleplay and his from within the game.

"Should this happen, two rpgs will link, however."
This outright states what the end game is.

I hold no quarrel with you, [@Avadon], but you need to realize it is almost universally, across many cultures, considered impolite at best to forcibly insert your own works into someone else's projects and games. The equivalent of walking into someone's house on D&D night, sitting down at the table, and declaring you are part of the group.

This is a matter of common courtesy. The correct way to approach something like what you want to do is send a private message to the game master, discuss it with them, and ask permission.
