I searched and didnt see this specific question asked but if your path has a telegate on it, do you have the ability to pass by it or do you have to enter the telegate and resolve it? I may be misreading but I am assuming that if its in your path you have to enter it.
You have to choose (or use previously chosen) pilot number. If that number exists on a telegate, you automatically teleport to it. (Could be the one that you are passing over.) If the pilot number doesn't show on a telegate, there is no effect.
There's an artifact called Gate Lock that you can engage for the entire turn to avoid activating telegates and there is another Jump Something that lets you go to a gate from anywhere if you roll its number.
