This is just speculation at the moment due to all of the footage of the taken king being *a work in progress* but in the "we are guardians" trailer multiple fallen ketches can be seen flying alongside guardians and awoken in order to seemingly confront Oryx's fleet. This is at 1:57 in the video.
Just saying.
This doesn't seem to be common knowledge but feel free to correct me if it is!
