Crystal Portal
The normal security access options apply. Double-clicking on the portal brings up directions that tell you that the portal will allow you to teleport directly to a bank or a moongate.
For the Trammel ruleset, say the city's name followed by "mint." For a moongate, say the gate's name and "moongate." For Felucca, follow the same two rules, with the addition of the word "fel" in front of the town or moongate name, e.g., "fel minoc mint" or "fel minoc moongate." The book of directions that comes up when you click on the portal provides a list of city and moongate names. It also says the normal teleportation rules apply, e.g., criminal, flagging, weight, etc.
The portal's globe is white. Screen shot shows the tooltip info and security options.
If you use the portal to go to a moongate, you arrive hidden. If you use it for a bank, you arrive in front of the bank, I think (have only used it to go to the Minoc bank so far). It works VERY quickly. It's an absolutely awesome reward!
