It is the only way to get from D to The Core of Everything. However, if you use it and can’t access TCoE, you get bounced to Thingk. If you can’t fit in thingk, you are sent to WMYDTTMV. If you can’t go there, you die. If you can’t die, you get sent to the Wikiverse. If you can’t, then you can’t go through the snek bridge now leave me alone.
