Northern Settlement
The settlement is commonly thought as the main area in TU. Here you have access to the an Assembly, Kangaskhan's Storage, as well as a healing point (Toren's House).

There is also a Purple Kecleon here who runs a shop and sells items for Poké. Notable as this is the only shop in TU that still uses Poké, as all other shops in TU use Ekop - TU's exclusive currency.

To go to this area, go North East from the Central Fork.

Central Fork
This is the central part of TU, which is the connection to all the areas in TU.

Mansion
There is a mansion located northwest in the Central Fork. There's nothing special about this place except that there is a room that you will get a warning not to enter when you go to it.

This is one of the main features in TU. In this market, you can buy items with Ekop - the exclusive currency in TU.
