Your first Land and House package can be bought on the Marketplace with SOM tokens and will be set as your home house called the Players’ Quarters. Then you can buy as many Land and House packages as you wish in order to sell them later to new players or to create special farming zones that will allow you to stake SOM tokens with much higher APY.
Keep in mind that your house in SOULS OF MΞTΛ grants you access to all the NPCs and Play Modes regardless of the settlement level you live in.
