Someday you are going to find that isn't enough.

The vision disappears as instantaneously as it formed, and you are left standing where you were, sword in hand. It makes you feel strong.

You've acquired Yamato and seem to inherently know how to use it. That is, a sense of how to go about fighting with a katana, and that it is made to cut through anything, even space, even a soul. There wasn't a way back, but you may have found one.

You've unlocked teleportation! Go wherever the heck you want, toplevels will be unscreened.
