Quote from mzxrules:
We don't ever warp the bridge, we warp to the other side of the gorge with BiTE. BiTE to Kakariko has been known for some time, but the difficulty has been getting over to the Twilit Messenger side of Kakariko Gorge. If you don't kill them you don't get the ability to warp on the map screen, making it impossible to beat the game, and you can't delay killing them because they disappear once the Kakariko twilight is cleared.
