He could use it either way, but on the whole tends to use it to defend the other players! [ From what she's seen, anyway. Besides, god tiers are pretty darn immortal anyway, so long as they're careful. ]

The first player in a chain has to be a client player, because to enter the game you need a server player running your game. We started out with two teams - or, rather, everyone else believed we started out with two teams. [ she was madam puppetmaster for half of the game, although she was also being directed by the dead, so. Yeah. ] A red team and a blue team. [ ...and there's a small smile there. ]

The first player for the red team was Karkat; for the blue team it was Equius. The server player - Terezi and myself, respectively - is responsible for deploying game-relevant items and building upwards towards the "gate", which takes you to the next level. The thing about the game is that it is, in essence, a way to save the lives of the players from meteor strikes - and, to skip a lot of plot, it is how we were all born!

So once you get someone into the game it is imperative you get into the game, or you'll, well, die. So each player is a server player to another player and a client to another player; it forms a chain.
