Ambassador.

Yes, in Deltarune, the Underground has a door. It's currently locked, but you can visit it at the extreme south point in the town, and has ominious sound coming from it.

Remember that there are at least two ways in Undertale to get into the monster world.

The first way was to fall from Mount Ebbott, which is how Chara entered the realm.

But Asgore's castle isn't in the Ruins, it's far to the east. Yet before fighting Frisk, he shows him a light-filled hallway that he calls The Barrier.

In Asgore's garden we see light streaming onto the floors from holes overhead. The outside world is very close here, with only the Barrier in the way.

And Asriel simply walked out of the Underground carrying Chara's body, and quickly ended up in her village. Then walked back in after resisting Chara's attempts at revenge.

The Waterfall Glyphs talk of a time when there we NO entrances or exits out of the monster world. But by the time of Undertale, there are at least two, located in the Ruins and past Asgore's caslte.

The world has changed since then. Perhaps there was an earthquake, or rock simply eroded since that time?
