Lion's Arch & Battle Isles, where are they?

Sorry to be a bother, Iam haveing a hard time getting to the location of this weekend's PvP Factions Event!! I now know that it is on Battle Isles, but I can't seem to find it or get there.!! I know that it is about half over ,but still would like to observe it..! I know to press "B" ,But donot see it ,or maybe I do & don't know it!!
Thanks

Look on your map towards lion's arch/kryta, off the seaboard of lion's arch is a "Travel" icon, big ship, can't miss it when zoomed in. Use this to travel to the Nameless Isle

and when you got a pvp character you will automatically be at the Battle Isles
