Area boundary/Portal jumping project

This is a project to find and document which portals can be shadow stepped through without triggering the normal rezone through use of the skills Heart of Shadow and Viper's Defense. As a result of the skill updates on May 14, 2009, crossing portals without triggering the normal rezone has been made substantially easier than it has been in the past. This project aims to take advantage of this to discover interesting and useful features, especially in case ArenaNet decides to revert or otherwise change the functionality of these skills.

Test Procedure

 * 1) When flagged too close a portal, a hero will teleport back to the player character and the flag will automatically be cleared.  Flag the hero as close as possible to the portal without this happening.  This will let you determine the real position of the portal, which is often different from the visible haze or vortex.  (Thanks for pointing this out, Vipermagi.)
 * 2) Assuming your character is the one using the skill Heart of Shadow or Viper's Defense, stand where the hero is flagged and face straight away from the portal.
 * 3) Use your reverse view key (probably 'z') to check for any obstructions directly in your path.  If there are any, start over and choose a better position.
 * 4) Activate the relevant skill and see if you zone or if you simply appear on the other side of the portal.  If you appear on the other side of the portal, see what you can explore and document it.  If you rezone, please make one more attempt to confirm you can't shadow step through successfully.  Some require you get very close to the portal and angle for the best shadow step possible.
 * Alternatively, a hero can use either of these skills as well. Position that hero as close as possible to the portal, move so he or she is directly between you and the portal, and order the hero to activate the relevant skill.  If it works, you will need a skill that allows you to shadow step to his or her location to see what is explorable.
 * Update this page with your own results. Please try to list results in a similar manner as seen here, and feel free to add notes on any anomalies or interesting features you see.  Please, also, do not change any results from "no rezone triggered" to "triggered normal rezone."  In other words, please assume good faith on the part of editors that they did indeed get through, and if you are in serious doubt, use the talk page.
 * The ultimate aim is to update the relevant location pages and the Grandmaster cartography guide with the useful tricks we discover. Additionally, we want to update the ends-of-the-world we discover on the recently created End of the world page.

Legend

 * Portal Locations are listed in bold when an editor has successfully shadow stepped through the portal without triggering a rezone.
 * They are also listed in italics when some useful benefit has been discovered for doing this. Examples include mob-free exploration of a zone or access to otherwise unexplorable or unreachable areas.
