Where are fast travel points?

[Julungo]

There's a mission that asks you to find teleport locations in each kingdom, but swear I've scoured the whole map and can't find any. Where should I be looking in each region?

Clockwork Kingdom - next to the purchasable house, to the north of Ferropolis.
Endless Realm - to the south of Sepulchre, right below the cliff on which Lord Rhydder's house is.

Thank you! That helped me nab those two. Are there any other fast travel points in the game or is that all of them?

There you go.

Those two are all that are needed for that quest.
As for others: one is in Pwyll, near Vela's fortress - look for a door on the map, it's on the northern side of that wall. And the last one is in Hallow Town, behind the tower in the upper part of the town. Five total.
