The ZoS Alliance 
The Celestial Order of Light [CooL]
Leader: Meiko Isamura
Website: N/A
[CooL] started in October 2007, founded by officers and members of a previous PvX guild who wanted to make a PvE Hard Mode focused guild. CooL members are a mix of players from the USA, Canada, Europe, and Australia and are either players who have finished their normal mode titles and now want to learn and focus on hard mode or experienced hard mode players who want to be in a guild with members who have similar goals as themselves. Almost every member is either a working professional or college student who loves Guild Wars. Our most common activities are GWEN dungeons, Guardian titles, Vanquishes, and DoA runs. Most of our members are working on reaching the highest rank of the KoaBD title track before GW2 comes out.

The Knights Templar [KT]

Website: KT's Fansite
KT was formed late in 2003 by a group of friends who had previously gamed together in Diablo II and has been a productive and valuable guild in the Alpha Test since. To this day KT remains a guild dedicated to close friendships, and it even includes a few family groups. The Knights Templar has a strong community focus, both within the guild and for those who they meet online. This is reflected in everything KT members do, from their operation of a fansite to including non-members in groups for missions or PvP play.
Shadow Knights of Balthazar [SKOB]

Website: SKOB's Website
SKOB is old, very old. It was formed from merging FF and iPOA guilds that were created at the beginning of GW. We maintain a strong atmosphere of friendship and good behavior. We will sacrifice size for quality. We appreciate good play but understand mistakes and don't get upset easily. To us, the feelings of the person behind the keyboard is more important than a couple of pixels on a screen.
The in-game ZoS Alliance has pledged its allegiance to the Luxon
Faction of Cantha.
Alliance Rules
Although there are no laid out rules, prospective guilds are asked to read over the ZoS Code. Alliance Chat should be kept respectful with a minimum of swearing, never to be directed at someone. Alliance Chat is not for begging/spamming for help or to buying/selling items either.
