The Isle of the Nameless is an explorable area on The Battle Isles. It serves as a tutorial and training area. Several NPCs ("Masters") of the Zaishen Order provide information about Guild Wars concepts and game mechanics. The Isle also features a number of hostile level 20 members of the Zaishen Order, suitable for practicing against. The Isle and the Menagerie are the only explorable areas a PvP character may visit.
