The Wings of Horus allow for one time, one way travel to a pre-determined point without spending the user's travel time. They are a normal inventory object, so they can be passed from one avatar to another as with any other object. There are two basic things that can be done with them: Tuning and Travel.
A pair of Wings of Horus is very simple to tune. Have them in your inventory (should be “Wings of Horus: Untuned”), bring up your personal menu, and then Navigation, you should see an option to “Tune Wings of Horus”. You will be prompted to enter a name; this can be anything you choose. Once you click “OK” that pair will be tuned to your current location. Once tuned, they are not re-tunable, so be careful to set them to the location you really want.
You can use a pair of Wings of Horus very simply, under the Navigation menu “Travel on Wings of Horus”. This will instantly transport you to location to which that pair was tuned. It is that simple.
Missing - how does one obtain suck items ? Are they rewards ?
These are given out as rewards during events. I have only seen them as lottery prices, meaning everyone participating has the same chance to get them. ~ Baldur
