Guild Wars 2

Hello guys I am rerolling my guardian and want the look to be a dark evil style Chaos Marine. Maybe a good side with Blood Angels.

As a massive 40k fan, and want to bring it to Guild Wars 2

Go with a Norn character.

There is also a guild back banner:

or a “Jump pack” http://wiki.guildwars2.com/wiki/Decorative_Molten_Jetpack

Alternatively if you go with a Warrior instead of a Guardian you get lots of nice battle standards

For a Chaos Marine, it’s probably a case of mixing a few sets, eg the Armageddon Karma set: http://wiki.guildwars2.com/wiki/Armageddon_armor/Heavy

This hammer is perfect for any servant of Chaos
